PART I

Item 1.  BUSINESS

	   Dionex Corporation* designs, manufactures, markets and
services analytical instrumentation and related accessories and
chemicals.  The Company's products are used to analyze chemical
substances in the environment and in a broad range of industrial
and scientific applications.  Since July 1, 1998, there have been
no material changes in the mode of conducting the business of the
Company.

	   Industry Segment Information

	   The Company operates in a single industry segment
consisting of analytical instruments and related services.

	   Products

	   Dionex develops, manufactures, markets and services a
range of chromatography systems, sample preparation devices and
related products that are used by chemists to separate and
quantify the individual components of complex chemical mixtures
in many major industrial, research and laboratory markets.
Typically, the Company's chromatography systems consist of
several components including a specially designed liquid pumping
and flow system, a sample injection system, a separator column, a
suppressor or other post-column device, a detector and a data
collection and analysis system.  These components are designed to
be modular so that systems can be configured to meet the
particular analytical requirements of individual customers.
Moreover, individual components may be sold separately to
existing customers that wish to expand their systems.

	   The Company's chromatography systems are currently
focused in several product areas: ion chromatography (IC), high
performance liquid chromatography (HPLC) and sample extraction.
In addition to these product areas, the Company develops and
manufactures columns, detectors, data analysis systems and other
products.  Each of these product areas is described below.

Ion Chromatography and HPLC - Ion Chromatography is a form of
chromatography that separates ionic (charged) molecules, usually
found in water-based solutions, and typically separates and
detects them based on their electrical conductivity.  The sale of
Dionex IC systems and related columns, suppressors, detectors,
automation and other products accounts for a majority of the
Company's revenues.
     ---------------------
     *	Unless the context otherwise requires, the terms
		"Dionex" and "the Company" as used herein include
		Dionex Corporation, a Delaware corporation, and its
		subsidiaries.  Dionex was initially incorporated
		in California in 1980.  In 1986, the Company
		reincorporated in Delaware.

<PAGE>
	  Dionex IC products are used in a wide range of
applications, including environmental monitoring, corrosion
monitoring, evaluation of raw materials, quality control of
industrial processes, quality control of pharmaceutical and
industrial products, research and development, and regulation of
the chemical composition of food, beverage and cosmetic products.
Major customers include environmental testing laboratories, life
science and food companies, chemical and petrochemical firms,
power generating facilities, electronics manufacturers,
government agencies and academic institutions.

	  HPLC is a form of chromatography that separates molecules
such as proteins, carbohydrates, amino acids, pharmaceuticals and
chemicals and identifies them by measuring the amount of light
that the molecules absorb or emit when exposed to a light source.
The Company's customers include biological research and
biotechnology groups, pharmaceutical and other industrial
companies.

DX-120 IC System

	  In fiscal 1996, the Company introduced the DX-120, a
cost-effective IC system for customers that need simple,
dedicated instrumentation for routine ion analysis.  The DX-120
was designed for improved reliability and automation, allowing
for quick set-up, simple operation and high quality isocratic
performance.  The DX-120 is marketed worldwide.

DX-500 IC and HPLC Systems

	  In fiscal 1994, the Company first introduced the DX-500
Series of chromatography systems for IC and HPLC in the North
American and European markets.  In fiscal 1995, the DX-500 line
was introduced in Japan and is now marketed worldwide.  The
modular, high performance system offers various configurations
designed to meet the needs of numerous IC and HPLC applications.
The DX-500 Series offers both quaternary gradient and isocratic
pump capabilities, in either PEEK (polyetheretherketone) or
stainless steel and several detection modes based on
conductivity, electrochemistry and optical absorbance.  This
versatility of detection and pumping capabilities allows
customers to perform a wide range of IC and HPLC applications.
In fiscal 1997, the Company introduced the LC25 oven, an oven
that features both conductive and convective heating to
facilitate temperature control of columns, cells and suppressors.
In fiscal 1998,the Company enhanced the DX-500 product line by
introducing the GP50 and IP25 pumps.  These pumps are the second
generation of pumps in the DX-500 product line and are designed




4
<PAGE>
to provide more reliable flow and gradient accuracy and
precision.  In fiscal 1998, the Company introduced the EG40
Eluent Generator, a module for use with the DX-500 system.  The
EG40 generates high-purity eluents on-line using only deionized
water as the carrier.  The benefits of the on-line eluent
generation is improved results by eliminating interferences,
enhancing sensitivity and providing greater flexibility.

In March 1999, the Company introduced the AAA-DirectTM Amino Acid
Analysis system based on the DX-500 platform, which greatly
simplifies the separation of amino acids along with amino sugars,
phospho-amino acids and simple sugars.  Unlike other products,
the AAA-Direct can accomplish this in a single run without any
pre-column or post-column derivitization.

Summit HPLC System

	  In October 1998, the Company significantly broadened and
strengthened its HPLC product offering with the acquisition of
Softron GmbH, a privately held German company, and our subsequent
introduction of the SummitTM HPLC System and CHROMELEONTM
Software in March 1999.  The latest in HPLC instrumentation and
chromatography software, these new products combine advanced pump
technology, a high performance autosampler and a variety of high
sensitivity detectors with the most powerful and flexible data
system available.  The Summit HPLC System includes a versatile
P580 dual piston pump designed for both high pressure and low
pressure gradient capabilities.  The Summit product line also
includes a high sensitivity UV-VIS absorbance detector, the
UVD 170S detector, and a world-class photodiode array detector,
the UVD 340S.

Process Instrumentation

	  In fiscal 1998, the Company began shipping the DX-800, the
next generation continuous on-line monitoring system.  The DX-800
uses industry standard PC-based automation, similar to that used
in laboratory chromatography.  Major applications for the
Company's DX-800 are in the power industry for the continuous
monitoring of corrosive contaminants in boiler water, the
semiconductor industry for continuous monitoring of contaminants
in high purity water and continuous monitoring of biological and
chemical synthesis processes.  The DX-800 is marketed worldwide.

<PAGE>
Sample Extraction  - The Company offers the ASE? 200 system for
automated sample extraction.  In fiscal 1995, the Company
introduced this new extraction technology called Accelerated
Solvent Extraction or ASE.  The ASE 200 system extracts solid
samples using common solvents at elevated temperatures and
pressures.  The ASE 200 system extracts solid samples in an
automated fashion using the same solvents used in traditional
soxhlet techniques. Competitive techniques include soxhlet,
sonication, microwave extraction and supercritical fluid
extraction.  The ASE 200 system offers several advantages over
other solvent based extraction techniques including lower solvent
consumption, reduced extraction time, higher throughput through
automation and ease of use.  ASE 200 systems are used worldwide
for a number of environmental, industrial and food and beverage
applications.  In fiscal 1997, the Company enhanced its ASE 200
system by introducing the ASE 200 Solvent Controller Module,
which automates the delivery of multiple solvents to the ASE 200
system, and Auto ASE, an add-on software feature which allows
control of up to eight ASE 200 systems from one location, as well
as methods storage and documentation.  In fiscal 1999, the
Company introduced several new applications for the ASE 200.
These applications include time and labor savings for the
extraction of polymers and environmental samples.

Automation Products - As part of its efforts to make chemical
analyses simpler, faster and more reliable, Dionex offers a
family of products that automate sample handling, system
operation and data analysis for chromatography systems.  These
products include PeakNet, PeakNet PA for Process Analysis and
CHROMELEON.  In addition, several automated sample injection
modules are available for IC and HPLC applications.

	  In fiscal 1994, the PeakNet PC-based Chromatography
Workstation was introduced.  PeakNet is the Company's latest
release of Windows-based applications for chromatography.
PeakNet Workstations are multi-featured, high performance
computer systems that automate control, data acquisition,
analysis and reporting for the DX-120, DX-500 and DX-800 systems.
In fiscal 1996, the Company introduced PeakNet 4.3, which offered
new capabilities including data smoothing options to reduce noise
and enhanced reporting formats to meet the changing documentation
requirements of our customers.  In fiscal 1997, the Company
introduced its latest version of the software, PeakNet 5.0, a new
generation 32-bit automation product designed for use with
Windows 95 and Windows NT.  In fiscal 1998, the Company enhanced
its PeakNet chromatography software by introducing PeakNet 5.1.
This release added new capabilities to the PeakNet software,
including full control and support of the EG40 and enhanced
reporting capabilities.



6
<PAGE>
	  The Company introduced in fiscal 1999, as part of the
Summit HPLC system, the CHROMELEON Chromatography Data System.
Chromeleon is a 32-bit application designed to run on Windows 95,
98 and Windows NT and even mixed platforms.  CHROMELEON operates
most liquid and gas chromatography systems from a single user
interface.  It is an easy to use, flexible data system with a
built-in SQL database and client/server architecture.

	  In fiscal 1994, the universal interface (UI20) module was
added to PeakNet.  It allows PeakNet workstations to accept data
from other Dionex instruments, as well as instruments
manufactured by other vendors.  A revision of the PeakNet
software was also introduced at that time to support the new
interfacing capabilities.

	  In fiscal 1994, the Company introduced the AS40 Automated
Sample Injection module (AS40).  The AS40 is a low-cost, metal-
free, rugged automated sample loading device designed especially
for ion chromatography applications.  The AS40 can be used with
the DX-120 and DX-500 series.

	In September 1998, the Company introduced the AS50 Auto-
Select Autosampler for use with the DX-500 ion chromatography
system.  The AS50 Autosampler is a high-performance, random vial
access autosampler with automated sample preparation.

	The Company also introduced the Gina 50 autosampler as part
of the Summit HPLC system.  The Gina 50 offers an innovative
"split-loop" injection system that provides for accurate and
highly reproducible injections.  The removable carousels and
programmable needle depth allows the Gina 50 to accommodate a
variety of sample vials and sizes.

Columns and Suppressors - A chromatography column generally
consists of a hollow cylinder packed under high pressure with a
chemical resin.  The column's function is to separate various
chemical components in a sample.  The Company develops and
manufactures its own resins using proprietary processes.  Dionex
currently manufactures and markets a broad range of column types
designed for particular applications in the liquid chromatography
market.








7
<PAGE>
	Several consumable products were introduced in fiscal 1999,
including two anion exchange columns, the IonPac(r) AS16 and the
IonPac AS17.  The IonPac AS17 column separates analytes in water
faster, more selectively and more reliably than other columns on
the market.  The IonPac AS16 performs rapid isocratic separation of
polarizable anions without the use of solvents or other eluent
modifiers.  Both columns are designed to enhance performance when
used with our EG40 Eluent Generator.  In addition, the Company
introduced two cation exchange columns, the ProPacTM WCX-10 and
ProPac SCX-10, to analyze proteins with small differences in
charge.  The columns are ideal for the characterization or quality
control of closely related proteins in biotechnology,
pharmaceutical and food and beverage applications.

	These products follow a steady stream of columns and
chemistries introduced in the previous two years, including the
AS11-HC, IonPac AS15, IonPac ICE-Borate, IonPac AS9-HC and IonPac
CS15.  These products cover a range of applications.

	In addition to columns, Dionex manufactures suppressors that
are used to enhance detection in ion chromatography.  The Company
has proprietary positions in the technology of suppression used in
ion chromatography as well as in the application of suppression
techniques.  The Company's suppressors lower background
conductivity while allowing separations using higher capacity
columns and more concentrated eluents (liquids used to carry a
sample through a liquid chromatography system).  In fiscal 1993,
Dionex enhanced its suppression technology with the introduction of
a new AutoSuppression product.  The product, called the Self-
Regenerating Suppressor (SRSTM), enhances IC performance while
operating with low maintenance requirements.  In fiscal 1997, the
Company introduced the SRS-II, designed to allow use with a wide
range of solvents at various temperatures.

	In fiscal 1998, the Company introduced the SRS-Ultra, the next
generation in the SRS line of suppressors.  The SRS-Ultra provides
superior performance for trace level ion chromatography.

Detectors - Detectors are used to measure the quantity of various
sample components after they have been separated in a
chromatography column.  Dionex currently offers several detector
products based on conductivity, electrochemistry, fluorescence and
absorbance, including a photodiode array detector introduced in
1995.  This range of detectors is designed to meet customer
requirements for analysis of organics, inorganics, metals, amino
acids, biological compounds and pharmaceuticals.  The Company
introduced as part of the Summit HPLC system, the UVD 170S and UVD
340S detectors.  The UVD 170S simultaneously monitors four
wavelengths providing the highest sensitivity available in a multi-
channel UV-VIS detector.  The UVD 340S is a technologically
advanced high sensitivity photodiode array detector for HPLC.  The
UVD 340S offers high sensitivity without sacrificing spectral
resolution.

Service and Other -  The Company also generates revenue from its
Customer Service organization through service contracts, spare part
sales, customer training and sales of other products and services.
(See Technical Support, Installation and Service below.)

Marketing and Customers

	The Company's market strategy is twofold.  First, in those
applications where Dionex technology is well established, the
Company works to increase demand for its chromatography systems
through direct mailings, advertising in trade publications,
seminars and workshops, conferences and expositions, and direct
sales calls.  Growth in these markets results from identifying new
customers in existing sales regions, extending geographic
penetration and increasing demand for the Company's products and
technical support capabilities among existing customers.

	The second component of the Company's marketing strategy is to
work closely with existing and potential customers to develop new
applications.  Technical support staff assist such customers in
problem definition, development of new applications needed to solve
problems and providing user training and ongoing user support.  By
combining this support function with direct sales efforts, the
Company works to increase the range of applications and the
potential market for its products.

	The Company currently markets and distributes its products and
services through its own sales force in the United Kingdom,
Germany, Italy, France, the Netherlands, Belgium, Switzerland,
Austria, Japan, Canada and the United States.  In each of these
countries, the Company maintains one or more local sales offices in
order to service customers in regional markets.  In other
international locations where it does not have a direct sales
force, the Company has developed a network of distributors and
sales agents.

The Company's products are used extensively in environmental
analysis and by the pharmaceutical, life science, biotechnology,
chemical, petrochemical, power generation, food and beverage and
electronics industries.  Its customers include a number of the
largest industrial companies worldwide, as well as government
agencies, research institutions and universities. Geographically,
sales to customers outside of North America accounted for 62% of
consolidated sales in fiscal 1999, 57% of consolidated sales in
fiscal 1998 and 61% of consolidated sales in fiscal 1997.  No
single customer accounted for 10% or more of the Company's sales in
fiscal 1999, 1998 or 1997.






9
<PAGE>
	Demand for the Company's products is dependent upon the size
of the markets for its chromatography systems, the level of capital
expenditures of the Company's customers, the rate of
economic growth in the Company's major markets and competitive
considerations.  There can be no assurances that the Company's
results of operations will not be adversely impacted by a change in
any of the factors listed above.  The Company believes that demand
for its products does not exhibit any significant seasonal pattern.

	Dionex manufactures its products based upon its forecast of
customer demand and maintains inventories of completed modules in
advance of receipt of firm orders from its customers.  Orders are
generally placed by the customer on an as-needed basis, and
products are usually shipped within four to six weeks after receipt
of an order.  Dionex does not maintain a substantial backlog, and
backlog as of any particular date may not be indicative of the
Company's actual sales in any succeeding period.  The level of
backlog at June 30, 1999 was $23.7 million and at June 30, 1998 was
$18.4 million.

	Competition

	Competition in the Company's business segment is based upon
the performance capabilities of the analytical instrument,
technical support and after-market service, the manufacturer's
reputation as a technological leader and the selling price.
Management believes that performance capabilities are the most
important of these criteria.  Customers measure system performance
in terms of sensitivity (the ability to discern minute quantities
of a particular sample component), selectivity (the ability to
distinguish between similar components), speed of analysis and the
breadth of samples that the system can effectively analyze.
Management believes that Dionex enjoys a favorable reputation in
terms of performance capabilities, technical support and service.

	Companies competing with Dionex in the analytical instruments
market include Hewlett-Packard Company, Perkin-Elmer Company,
Varian Associates, Inc., Shimadzu Corporation, Thermo Instruments
and Waters Corporation. The Company believes no single competitor
has a dominant position in the analytical instruments market.

The Company believes it has a major position in IC, one of many
different analytical techniques.  Dionex IC systems generally
compete with a number of analytical techniques used in identifying
and quantifying ionic and polar compounds.  The two primary sources
of competition for ion chromatography are conventional manual and
automated wet chemistry procedures and certain modified liquid
chromatography systems.  Some suppliers of liquid chromatography
systems have developed a single column ion chromatography (SCIC)
method that does not use a suppressor device.  SCIC methods compete
favorably with Dionex ion chromatography for the analysis

10
<PAGE>
of a limited number of ions and in situations when chemical
composition of the sample is not complex or when high sensitivity
is not required.  The introduction in 1993 by the Company of
AutoSuppression technology considerably improves the ease of use
of chemical suppression.  In addition to SCIC products, the
Company's competitors also offer other products to compete in ion
analysis and chromatography products using technology similar to
that offered by the Company in earlier generation modules during
the 1980's.

	Competitors of the Company in HPLC include such vendors as
Hewlett-Packard Company, Waters Corporation, Alltech Associates,
Lachat and other smaller companies. The Company's newly
introduced Summit HPLC system competes directly with other
manufacturers' HPLC systems in traditional HPLC applications.
Dionex believes that the Summit HPLC system has certain benefits
over competing systems, including advanced pump technology and a
high performance autosampler.  Coupled with the CHROMELEON
software package, this system provides customers a state-of-the-
art HPLC system for their analytical needs.

	The Company's DX-500 Series also competes directly with
other manufacturers' HPLC systems in certain traditional HPLC
applications.  Dionex is a relatively new entrant in the highly
competitive HPLC and biological separations markets. Nonetheless,
management believes that the DX-500 Series has certain benefits
over competing systems, including a non-metallic flow path and
the capability of performing gradient ion chromatography, as well
as HPLC, on a single analytical system.

	The Company's ASE 200 competes directly with standard
soxhlet, sonication, supercritical fluid extraction and microwave
extraction techniques provided by other companies.  Management
believes that the ASE 200, has certain benefits compared to
competing techniques, including faster extraction time, reduced
solvent usage and built-in automation.

	The Company believes that competition in the ion analysis
market will continue to increase in the future.  Moreover, the
Company's entrance into the HPLC and sample extraction markets
has resulted in increased competition. Many of the companies
whose products compete with those of the Company have
substantially greater financial resources and larger technical
staffs and sales forces at their disposal.  There can be no
assurances that the Company's marketing and sales efforts will
compete successfully against such other companies in the future.






11
<PAGE>
	Patents and Licenses

	The Company has an extensive patent portfolio covering
certain of the Company's products.  The primary benefits of
patents are presently limited to the United States and certain
other foreign countries where patents have been issued.

	As a matter of Company policy, the Company vigorously
protects its intellectual property rights and seeks patent
coverage on all developments that it regards as material and
patentable.  However, there can be no assurances that any patents
held by the Company will not be challenged, invalidated or
circumvented or that the rights granted thereunder will provide
competitive advantages to the Company.  The Company's patents,
including those licensed from others, expire on various dates
through 2011.  The Company believes that, while its patent
portfolio has value, no single patent or patent application is in
itself essential and that the invalidity or expiration of any
single patent would not have a material adverse effect on its
business.

	The Company regards its PeakNet and CHROMELEON software as
proprietary and relies on a combination of copyrights,
trademarks, trade secret laws and other proprietary rights, laws,
license agreements and other restrictions on disclosure, copying
and transferring title to protect its rights to its software
products.  The Company has no patents covering its software, and
existing copyright laws afford only limited practical protection.
In addition, the laws of some foreign countries do not protect
the Company's proprietary rights to the same extent as do the
laws of the United States.

	International Operations

	Financial information about foreign and domestic operations
and export sales required by Item 1 of Form 10-K is incorporated
by reference to Note 12 of the Notes to Consolidated Financial
Statements at page 35 of the Registrant's 1999 Annual Report to
Stockholders.  A copy of the applicable page is included as
Exhibit 13.1.

	The Company has subsidiaries in the United Kingdom, Germany,
Italy, France, the Netherlands, Belgium, Switzerland, Austria,
Japan and Canada. The Company's foreign sales are affected by
fluctuations in currency exchange rates and by regulations
adopted by foreign governments.  Export sales are subject to
certain controls and restrictions, but the Company has not
experienced any material difficulties related to these
limitations.  There can be no assurances that the Company's
results of operation will not be adversely impacted by
fluctuations in currency exchange rates in the future.


12
<PAGE>
	Manufacturing and Suppliers

	The Company produces chemicals and resins and assembles
systems and components in its California manufacturing
facilities.  The Company assembles the systems and components for
its Summit HPLC system in its German manufacturing facility.
Dionex has developed proprietary processes for the manufacture of
polystyrene-based resins and for packing columns with these
resins.  The Company believes that its resins, columns and
suppressor manufacturing know-how are critical to the performance
and reliability of its chromatography systems.  The Company
requires each employee to sign a nondisclosure agreement to
protect its proprietary processes.  However, there can be no
assurances that these agreements will provide meaningful
protection or adequate remedies for the Company's proprietary
processes in the event of unauthorized use or disclosure.

	The Company has emphasized a modular design for the
principal subsystems of its pumping flow systems, sample
injection systems, chromatography modules, detectors, and control
and data analysis systems.  The Company believes that this
modular approach has enabled it to meet the wide range of system
configurations required by its customers while effectively
managing inventory levels.

	Many components used in the Company's products, including
proprietary analog and digital circuitry, are manufactured by
Dionex.  Other components, including packaging materials,
integrated circuits, microprocessors, microcomputers and certain
detector and data analysis modules, are acquired from other
manufacturers.  Most of the raw materials, components and
supplies purchased by the Company are available from a number of
different suppliers; however, a number of items are purchased
from limited or single sources of supply, and disruption of these
sources could have a temporary adverse effect on shipments and
the financial results of the Company.  The Company believes
alternative sources could ordinarily be obtained to supply these
materials, but a prolonged inability to obtain certain materials
or components could have an adverse effect on the Company's
financial condition or results of operations and could result in
damage to its relationship with its customers.












13
<PAGE>
	Technical Support, Installation and Service

	Users of the Company's chromatography systems require
substantial technical support before and after the system sale to
ensure that analysis problems are resolved.  As part of its
support services, the Company's technical support staff provides,
typically at no additional cost, individual assistance in solving
chemical analysis problems.  The Company offers training courses
and periodically sends its customers information on applications
development. Chromatography systems sold by the Company generally
include a one-year warranty, installation and certain user
training, all at no additional cost.  Service contracts may be
purchased by customers to cover equipment no longer under
warranty.  Service work not performed under warranty or service
contracts is performed on a time and materials basis.  The
Company installs and services its products through its own field
service organization in the United Kingdom, Germany, Italy,
France, the Netherlands, Belgium, Switzerland, Austria, Japan,
Canada and the United States.  Installation and service in other
foreign countries are typically provided by the Company's
distributors or agents.

	Research and Development

	The Company's research and development efforts are focused
on increasing the performance of its chromatography and other
products and expanding the number of chemical compounds that can
be analyzed efficiently with its products.  Research and product
development expenditures were $14.8 million, $13.3 million and
$12.5 million in fiscal 1999, 1998 and 1997, respectively.  The
Company pursues active development programs in the areas of
system hardware, applications, computer software, suppressors,
resin and column technologies.  There can be no assurances that
the Company's product development efforts will be successful or
that the products developed will be accepted by the marketplace.

	Environmental Laws and Regulations

	Compliance by the Company with federal, state and local
environmental laws during fiscal 1999 had no material effect upon
capital expenditures, earnings or its competitive position.

	Employees

	Dionex had 799 employees at June 30, 1999, compared with 715
employees at June 30, 1998.  The Company believes that its future
success depends in large part upon its continued ability to
attract and retain highly skilled employees.

		Several of the Company's properties are located in an
		area under investigation by the California Regional
		Water Quality Control Board (the "Water Board".)  The
		Water Board's investigation addresses the presence of
		Certain volatile organic compounds in portions of the
		Local groundwater system and focuses principally on the
		activities of several other companies located near the
		Company.  The Water Board review has encompassed the
		property acquired by the Company in July 1986.  The
		Company believes that any remedial work affecting the
		subject property will be performed by or at the expense
		of other parties responsible for any release of
		chemicals onto the property, or at the expense of the
		previous owner of the property.  As a result,
		management believes that any action required by the
		Water Board's investigation will not have a material
		adverse effect on the Company's financial position or
		results of operations.

NET SALES AND GROSS PROFIT. In fiscal 1999, Dionex (the "Company")
reported record sales and earnings for the 19th consecutive year,
excluding nonrecurring items. The Company's consolidated sales in
fiscal 1999 were $172.9 million, an increase of 15% compared with
$150.5 million reported in fiscal 1998. Sales in fiscal 1997 were
$142.1 million. The Company is subject to the effects of foreign
currency fluctuations, which can have an impact on reported sales
and gross profits. Currency fluctuations increased reported sales
by 1% in fiscal 1999 and reduced sales by 4% in fiscal 1998.

Sales growth in fiscal 1999 was attributable to strong growth in
our European and Japanese markets. Growth in the Company's North
American market was slower than in past years. The Company saw some
improvement in the fourth quarter in sales to the Far East as some
of the Asian countries start to recover from the financial crisis
that began in fiscal 1998. Sales growth in fiscal 1998 was fueled
by strong growth in North America and Europe in local currencies.
However, a strengthening U.S. dollar reduced the reported results
in Europe. Sales in the Far East declined slightly due to the
financial crisis and a stronger U.S. dollar.

Sales outside of North America accounted for 62% of consolidated
sales in fiscal 1999, 57% in fiscal 1998 and 61% in fiscal 1997.
The Company sells directly through its sales forces in the United
Kingdom, Germany, Italy, France, the Netherlands, Belgium,
Switzerland, Austria, Japan, Canada and the United States. Direct
sales accounted for 92% of consolidated sales in fiscal 1999,
compared with 90% in fiscal 1998 and 88% in fiscal 1997.
International distributors and representatives in Europe, the Far
East and other international markets accounted for the balance of
the consolidated sales. There were no significant price changes
during the three-year period.
18
<PAGE>
Gross profit in fiscal 1999 was affected by a nonrecurring charge of
$2.0 million related to the write-up of inventory acquired in the
acquisition of Softron GmbH (Softron). Excluding this charge, gross
profit was 68.1%, compared with 68.5% in fiscal 1998 and 69.4% in
fiscal 1997. Including this charge, gross profit for fiscal 1999 was
66.9%. Gross profit was lower in fiscal 1999 due to the inclusion of
Softron, whose products generally have a lower gross profit than the
historical Dionex product margins. Gross profit in fiscal 1998 was
negatively affected by a strengthening U.S. dollar.

OPERATING EXPENSES. Selling, general and administrative ("SG&A")
expenses as a percentage of net sales decreased to 31.2% in fiscal
1999, compared with 31.7% in fiscal 1998 and 33.3% in fiscal 1997.
SG&A expenses increased to $54.0 million, an increase of 13% in
fiscal 1999 from $47.7 million in fiscal 1998. The increase in SG&A
expenses was attributable to the inclusion of Softron costs since the
acquisition date and increased selling expenses. The Company
anticipates that SG&A expenses will be in the range of 30% to 34% of
sales in the near term.

Research and product development expenses were 8.6% of consolidated
sales in fiscal 1999 compared with 8.8% in both fiscal 1998 and 1997.
Research and product development expenses in fiscal 1999 increased
12% to $14.8 million compared with $13.3 million in fiscal 1998. The
increase was due to the inclusion of Softron costs since the
acquisition date and higher personnel and related costs associated
with various product development projects. Research and product
development expenses in fiscal 1998 increased 6% from $12.5 million
reported in fiscal 1997. The increase was attributable to higher
personnel and related expenses and project material costs. Research
and product development spending depends on both the breadth of the
Company's research and product development efforts and the stage of
specific product development projects. The Company anticipates that
the level of research and development expenses will remain in the 8%
to 10% range in the near term.

WRITE-OFF OF IN-PROCESS RESEARCH AND DEVELOPMENT ACQUIRED. Write-off
of in-process research and development acquired represents a
nonrecurring charge of $5.0 million associated with the acquisition
of Softron in October 1998 for technology that had not reached
technological feasibility and had no alternative future use.
The valuation of intangibles related to the acquisition was based
upon management's estimates of after tax net cash flow using a 25%
discount rate. The valuation gave consideration to the following: (i)
comprehensive due diligence concerning all potential intangibles;
(ii) the value of developed and core technology, ensuring that the
relative allocation to core technology and in-process research and
development were consistent with the contribution of each to the
final product; and (iii) the allocation to in-process research and
development based upon a calculation that only considered the efforts
completed as of the date of the transaction, and only the cash flows
associated with one generation of products currently in-process. The
valuation was performed by an independent valuation group and was
deemed reasonable in light of all the quantitative and qualitative
information available.
19
<PAGE>
The write-off of in-process research and development related to three
projects that were in development, had not reached technological
feasibility, had no alternative future use and for which successful
development was uncertain.

Two of the in-process projects were to design and build new liquid
chromatography modules. At the date of acquisition, the estimated
cost to complete these projects was approximately $900,000. The third
project was a new generation of software. At the time of the
acquisition, the estimated cost to complete was approximately
$750,000. The projects are currently scheduled to be completed in the
latter part of calendar 1999. Costs incurred by the Company through
June 30, 1999 were approximately $1.2 million.

There can be no assurances that the Company will be able to complete
the development of the products on a timely basis. Failure to
complete these projects could have an adverse impact on the Company's
financial condition or results of operations.

INTEREST INCOME. Interest income in fiscal 1999 of $917,000 was
$457,000 lower than the $1.4 million reported in fiscal 1998. The
decline in interest income was due to lower cash balances primarily
resulting from the acquisition of Softron. Interest income in fiscal
1998 was essentially unchanged from fiscal 1997. Higher yields on
invested cash in fiscal 1998 were offset by lower average cash
balances.

INTEREST EXPENSE. Interest expense in fiscal 1999 was $301,000, an
increase of 163% from the $115,000 reported in fiscal 1998. The
increase was attributable to short-term borrowings related to the
acquisition of Softron. Interest expense in fiscal 1997 was $85,000.

INCOME TAXES. The Company's effective tax rate for fiscal 1999 was
33.2% compared with 34.0% in fiscal 1998 and 34.5% in fiscal 1997.
The Company's effective tax rate is affected by the mix of taxable
income among the various tax jurisdictions in which the Company does
business. The Company anticipates that its effective tax rate will be
in the 32% to 35% range in the near term.

EARNINGS PER SHARE. Excluding nonrecurring acquisition related
charges, diluted earnings per share were $1.40, an increase of 19%
compared with fiscal 1998. Including these charges, diluted earnings
per share in fiscal 1999 were $1.20 per share, compared with $1.18 in
fiscal 1998 and $1.03 in fiscal 1997. The number of shares used in
computing diluted and basic earnings per share declined each year due
to the Company's stock repurchase program.

LIQUIDITY AND CAPITAL RESOURCES.

In fiscal 1999, the Company had cash and cash equivalents of $11.3
million. The Company's working capital was $34.8 million at June 30,
1999, compared with $35.7 million at June 30, 1998. Working capital
decreased in fiscal 1999 due to the acquisition of Softron. In
addition, the Company repurchased 501,500 shares of its common stock
for $14.9 million in fiscal 1999 under its stock repurchase program.
The Company repurchased 1,851,460 shares for $46.2 million in fiscal
1998 and 1,583,478 shares for $31.0 million in fiscal 1997.

Cash generated by operating activities was $31.1 million in fiscal
1999, compared with $27.9 million in fiscal 1998 and $27.0 million in
fiscal 1997. The increase in operating cash flows was due to higher
net income after noncash transactions, partially offset by higher
accounts receivable.

Capital expenditures in fiscal 1999 increased to $7.5 million,
compared with $2.5 million in fiscal 1998 and $2.6 million in fiscal
1997. The higher level of capital expenditures in fiscal 1999 was due
primarily to the addition of a leasehold right in Japan for $3.4
million and a new internal computer system.

At June 30, 1999, the Company had outstanding borrowings of $1.8
million and bank lines of credit totaling $35.5 million. The Company
believes its cash flow from operations, its existing cash and cash
equivalents and its bank lines of credit will be adequate to meet its
cash requirements for the near term.

The impact of inflation on Dionex Corporation's financial position
and results of operations was not significant during any of the
periods presented.

ACQUISITION

In October 1998, the Company, through a wholly owned subsidiary,
purchased all of the issued and outstanding shares of Softron, a
limited liability company organized under the laws of Germany, for
total consideration, including acquisition costs, of approximately
$24.7 million.

The acquisition of Softron was accounted for by the purchase method
and its results of operations have been included in the Company's
results of operations since the date of acquisition.

In connection with the acquisition, the Company recorded a
nonrecurring charge of $5.0 million for the write-off of in-process
research and development acquired. In addition, cost of sales in
fiscal 1999 included $2.0 million related to the sale of inventory
acquired which had been revalued as a part of the purchase
accounting.




21
<PAGE>
The Company initially expected to record a charge of between $10
million and $12 million for in-process research and development
acquired in connection with the Softron acquisition. However, in the
latter part of calendar 1998 the Securities and Exchange Commission
issued new guidance concerning the methods for determining in-process
research and development charges. In light of this new guidance, the
Company reported charges related to in-process research and
development substantially lower than originally anticipated.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards (SFAS) No. 133,
"Accounting for Derivative Instruments and Hedging Activities". The
statement establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments
embedded in other contracts and for hedging activities. It requires
that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those
instruments at fair value. SFAS 133 is currently effective for Dionex
in the first quarter of fiscal year 2001. Earlier application is
permitted. Management does not believe that this standard will have a
material impact on the Company's results of operations or financial
position.


EURO CURRENCY

On January 1, 1999, the countries of the European Union adopted a
single currency known as the "euro." The euro will become the legal
currency of these countries effective July 1, 2002. During the 31/2
year transition period, companies in these countries may conduct
business both in the euro and in their own currencies at a fixed
exchange rate. The Company has considered the potential impact of the
euro conversion on pricing, competition, its information technology
systems, currency risk and risk management. Currently, the Company
does not expect that the euro conversion will result in any material
increase in costs to the Company or have a material adverse effect on
its business or financial condition.

YEAR 2000 COMPLIANCE

Many older computer software programs refer to years in terms of
their final two digits only. Such programs may interpret the year
2000 to mean the year 1900 instead. If not corrected, those programs
could cause date-related transaction failures. Beginning in fiscal
1997, the Company started a process to review its internal systems
for year 2000 compliance. Testing of the internal systems was
substantially completed during fiscal 1998 and the Company believes
its current internal systems are compliant. Dionex believes the
products it is currently shipping are year 2000 compliant as well. To
date, the Company has spent approximately $150,000, primarily in
capital expenditures, to replace certain predecessor capital items.
The Company does not expect that any remaining remediation costs that
may exist will be material.
22
<PAGE>
The Company has made public statements to customers regarding its
state of year 2000 preparedness for its products; however, the
possibility of product liability claims still exists. To date, the
Company has received communications from many of its major customers
regarding their awareness of the year 2000 issue. Additionally, the
Company has contacted numerous vendors to assess their progress in
addressing the year 2000 issue. Based upon our assessments, testing
and the plans in progress, the Company does not believe that the year
2000 issue will have a material adverse effect on the Company's
financial position, results of operation or cash flows. However, the
Company does not have control over whether its vendors or customers
will make the appropriate modifications on a timely basis. If such
modifications are not made in a timely manner, the Company's
financial position and results of operations could be materially
adversely affected.

The Company is in the process of identifying contingency alternatives
for certain elements of year 2000 risk and the plan is intended to be
completed before December 1999. The plan will address vendor problems
as well as temporary remedies in the event of failure of company or
third party systems. The Company will continue to monitor its
business to determine if additional contingency plans need to be
developed. There can be no assurance that any contingency plans will
prevent a year 2000 problem from occurring. However, should the need
arise, the Company believes it has adequate resources and would use
them to resolve significant year 2000 issues in a timely manner.

FORWARD-LOOKING STATEMENTS

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS.

The Company is exposed to financial market risks, including changes
in foreign currency exchange rates, interest rates and marketable
equity security prices.

Foreign exchange risk arises from our exposure to fluctuations in
foreign currency exchange rates because our reporting currency is the
U.S. dollar and we derive approximately 54% of our sales by
transacting business in various foreign currencies. U.S. dollar-
denominated costs and expenses as a percentage of total operating
costs and expenses are much greater compared to U.S. dollar-
denominated sales as a percentage of total sales. As a result,
appreciation of the U.S. dollar against our major trading currencies
has a negative impact on our results of operations and depreciation
of the U.S. dollar against these currencies has a positive impact.

To mitigate its foreign currency exchange risks, the Company utilizes
derivative financial instruments. The Company hedges foreign currency
exchange risk on its intercompany receivable balances utilizing
foreign exchange forward contracts with high quality financial
institutions. The Company's foreign exchange hedging activities do
not subject the company to significant risk due to exchange rate
movements because gains and losses on these contracts generally
offset losses and gains on the underlying items being hedged. Using a
hypothetical adverse change in foreign currency exchange rates of 10%
(a weakening of the U.S. dollar), the fair value of these financial
instruments would decrease by $1.6 million. The Company does not use
derivative financial instruments for speculative or trading purposes.

The Company has investments in marketable debt securities that are
subject to interest rate risk. However, due to the short-term nature
of the Company's debt investments and the Company's intention to hold
these investments until maturity, the impact of interest rate changes
would not have a material impact on the Company's results of
operations or cash flows.

The Company is exposed to equity price risk on its investments in
marketable equity securities. These investments are classified as
"available for sale." The Company does not attempt to reduce or
eliminate its market exposure on these investments. A 10% decline in
the market price of the Company's investments would result in an
approximately $1.4 million decrease in the fair value of the
Company's "available for sale" securities. Although changes in equity
prices may affect the fair value of "available for sale" securities
and cause unrealized gains or losses, such gains or losses would not
be realized unless the investments were sold.

All of the potential changes noted above are based upon sensitivity
analyses performed on the Company's financial positions at June 30,
1999. Actual results may differ materially.
