Effortless Sample Preparation
Get to know perfectly harmonized concepts of sample preparation and analysis!
Remain flexible and cost-effective with a system that greatly minimizes idle
time and increases the throughput of AOX samples.

APU 28The automatic sample preparation system APU 28 allows
sample preparation for AOX determination according tothe column method. The individual samples are processed
immediately one at a time. The first samples are available
for analysis shortly after adsorption. The specifiedadsorption rate is maintained due to highly precise pumptechnology.

APU simThis automatic adsorption unit for preparing samples
for AOX determination according to the column method
provides simultaneous sample preparation of up to six
samples. Sample volume, wash volume and flow rate areadjusted individually and variably. Thanks to its robust
design and easy handling, water samples of all kinds areenriched on active charcoal in next to no time.

Extremely short and direct paths as well as the absenceof any valve technology minimize the maintenance effort.
System care and routine maintenance are done within a few
minutes.

AFU 3
For the automation of the batch method, the automatic
filtration unit AFU 3 is an indispensable part of theroutine. After the adsorption process, three samples can befiltered simultaneously with gas pressure and transferred
quantitatively to the filter container using a washingsolution.

In addition, the APU 28 SPE allows sample preparationaccording to the SPE method. Adsorption on the SPE
column, eluting and adsorption on the activated carbon
are done fully automatically and without any manualintervention. Simple and unrivaled!
A world-wide unique two-channel system: the APU 28 S
doubles the speed in sample preparation. Two samples areenriched simultaneously.
As a result, 28 samples can be prepared for analysis in one
run, without intervention and within short time – fully
automated and compliant with standard methods.
APU 28 S significantly speeds up sample preparation, thestep that significantly influences the speed of AOX analysis.

8Sample Feed – Reliable. Fast. Individual.
A multitude of samplers allows adaptation to individual needs – from manual
operation to fully automated sample feed for all applications.

Versatile automatic sampling systems
For efficient, convenient, and uniquely flexible operation,
diverse automatic sampling systems are available for thecomplete automation of the measurement procedure.
You can analyze samples prepared according to the column
or batch method with the quartz container. Without
retrofitting the system! In one sample sequence! With theoptional direct feed, you are able to analyze only the loaded
charcoal after pushing it out of the columns.

Advantages of the quartz container feed:■■ Protection of the sample from environmental 		impacts■■ Especially well-suited for trace concentrations of 		AOX
■■ Minimal AOX blank values■■ Particularly well-suited for small and medium-sized 		sample series■■ Less wear on the combustion tube

Advantages of the direct feed:■■ Especially well-suited for high AOX concentrations■■ Maximum sample throughput■■ Particularly well-suited for large sample series

9The fully automated samplers of the autoX series ensure an
unmatched sample throughput in the vertical and horizontal
operation mode. A special quartz container technology andthe sophisticated protective covering of the sampler shield
the charcoal from environmental impacts. An additional
purging of the sample rack with inert gas is not necessary.
The autoX samplers also allow the direct feed of samples,if required. Therefore, the charcoal is pushed out of thecolumns. With direct feed, you can use the maximum
capacity of the combustion tube and increase the sample
throughput.
In vertical operation mode, the samples are loaded via a gaslock. Completely maintenance-free, this provides a fast andreliable measuring process without complicated mechanics.
The autoX samplers are available in different versions
to optimally adapt the multi X® 2500 to your laboratory
requirements.
autoX 36
The automatic sampler autoX 36, for small AOX sample
series in the vertical mode, introduces up to 36 samples,
prepared according to batch or column method, into theinstrument within one sequence.

autoX 112
The autoX 112 allows an extremely high sample throughput
in the vertical and horizontal mode for large AOX sample
series using the column or batch method. In vertical mode,the charcoal is fed into the combustion system together withthe container or directly after pushing it out. In horizontal
mode, AOX samples can also be introduced via the boat
inlet. The analysis of the parameter EOX can be automatedin vertical operation by means of direct injection into thecombustion tube as well as in horizontal mode using theboat inlet. The optional flame sensor technology guarantees
residue-free combustion.
autoX 112 — Your Benefits■■ AOX/EOX vertical and horizontal■■ Automatic feed of up to 112 samples■■ Quartz container feed or direct feed■■ Racks for containers, sample vials, sample boats■■ Also suited for the TOC determination

Autoinjector
An autoinjector allows the exact dosing of EOX samples
using standardized filling volumes. The injection speed iscontrolled by the multiWin® software. You dose samples as
an autosampler.
Whether AOX or EOX, vertical or horizontal – with themulti X® 2500 you are flexible in application and efficient inoperation. The optimal combination of sample preparationand sample feed always guarantees flexibility, speed and low
operational costs for your requirements.

10Precise Analysis Made Easy
A patented measuring cell adjusted to match all measurement tasks guarantees
precise analysis. Even with large concentrations, overtitration is impossible. An
extremely dynamic operating range with increased sensitivity provides reliable
analysis of samples with unexpectedly high AOX concentrations.

Highly sensitive detection for precise results
The measuring cell of the multi X® 2500 has a compact androbust design. The optimal protection from the effects ofambient light, the self-cleaning silver anode and the uniquecooling system guarantee highest sensitivity, long-term
stability and an operator comfort you do not want to miss.
The measuring cell and the electrolyte are designed for
maximum sample throughput and adjusted to the operationof the automatic sampler. With multi X® 2500 you analyze
large sample series with intensely changing concentrations
without any special effort. No need for changing theelectrolyte. The patented detection of the multi X® 2500
meets all requirements of AOX analysis.

Software that reliably guides you to your goal
The self-explanatory multiWin® software is your personal
assistant and consultant. It easily guides through the entire
menu, from the system start to system shut-down, at theend of the working day. It monitors and controls all relevant
system parameters. It checks the system performance andthe analysis quality. It delivers a clear presentation of themeasurement results in individual analysis reports, andmuch more.

A special wide-range coulometer guarantees a wide dynamic
measuring range and enables the adaptation to diverse
analytical tasks while maintaining a unique sensitivity.
EOX determination in the trace range or high TX
concentrations in derived fuels are handled with ease.
Thanks to innovative ceramic technology, the multi X® 2500
is equipped with an extremely robust and durable electrode.
The combination electrode combines indicator electrodes
and a generator cathode in one. This requires no diaphragmor salt bridge and is therefore quickly ready for operation andmaintenance-free.
