Warning: Limitation of Liability
The ultimate responsibility of the consequences of use of toxic compounds
rests with the user. INFICON’s role is as a supplier of instrumentation toassist in the early detection of hazardous conditions involving suchcompounds.
It is vitally important to ensure that the 2020ppbPRO is maintained inaccordance with INFICON’s instructions and that proper calibration isregularly performed.
As with any complex device, the 2020ppbPRO is subject to failure and, while
INFICON has taken, and continues to take, all possible precautions to (a)reduce the possibility of failure, and (b) warn the user in the event of failure,
circumstances may occasionally occur in which there is a failure despite
such precautions on INFICON’s part. INFICON regrets that it cannot accept
liability for damages of any kind caused as a result of either failure of theuser to follow instructions or of the 2020ppbPRO to perform.

2020ppbPRO Overview

Figure 1. The 2020ppbPRO Instrument
The 2020ppbPRO measures the concentration of airborne gases and vapors thatcan be ionized by a photoionization detector. The 2020ppbPRO automaticallydisplays and can record these concentrations. The 2020ppbPRO does notdistinguish between individual compounds. The reading displayed represents
the total concentration of all photoionizable chemicals present in the sample. The
2020ppbPRO displays concentrations in units of ppb as well as ppm and Mg/M3.
The 2020ppbPRO operates automatically. The 2020ppbPRO display updates itself
once per second. You can read concentrations directly from the display.
The 2020ppbPRO will perform short-term exposure limit (STEL), time-weighted
average (TWA) and PEAK calculations when it is in INTERVAL mode. You can view
any of these results in INTERVAL mode.
The 2020ppbPRO has two datalogging options, Tag and Interval mode. Tag mode
allows the user to manually tag and store readings during a walkthrough. Interval
mode allows the user to datalog at selectable intervals of 1 second to 999 seconds.
In Interval mode, the STEL, PEAK and TWA are calculated. If you select Intervalmode, these values are automatically recorded in the 2020ppbPRO’s memory. The
2020ppbPRO can log up to 12,000 entries.

32 32

ISP-074-576-P1DIn Tag mode operation, the 2020ppbPRO prompts you to locate a site and then torecord a background and sample readings for the site. You can record up to 12,000
manual entries. There is no averaging of data in Tag mode.
Recorded data can be reviewed on the display or downloaded to a computer. Data
are recorded by date and time.
The 2020ppbPRO has 5 keys for instrument operation. The keys are used to set up
and calibrate the 2020ppbPRO. All information entered with the keys and stored in
the 2020ppbPRO’s memory is retained when the instrument is switched off. The
clock and calendar continue to operate and do not need to be reset when the
2020ppbPRO is turned on.

General Operation
The 2020ppbPRO is a microprocessor-controlled air monitor for measuring thepresence of photoionizable compounds in air at parts-per-billion levels. The block
diagram in Figure 2 shows the main components of the 2020ppbPRO.

Figure 2. The 2020ppbPRO Block Diagram
The microprocessor controls the components of the instrument and interprets andrecords the signal generated by the photoionization detector (PID). Recorded dataand setup information entered into the microprocessor’s memory are retained whenthe 2020ppbPRO is turned off.
A pump continuously pulls the air under test through the 2020ppbPRO’s PID. The
PID converts the concentration of photoionizable compounds in the sample into anelectrical signal. The microprocessor subtracts any background from the signal anddivides this signal by a sensitivity obtained by calibrating with a standard gas ofknown concentration. This concentration appears on the 2020ppbPRO’s display
and, depending on the values entered through the 2020ppbPRO’s keypad, an alarm
status may be displayed and an audio signal may be heard.
The 2020ppbPRO can detect thousands of different types of airborne gases andvapors and its response depends on the characteristics as well as the concentrationof each compound.
The 2020ppbPRO does not distinguish one type of compound from another,but displays a number indicating the total concentration of all photoionizable
compounds in the sample.

ISP-074-576-P1D

33

A standard of isobutylene at a known concentration may be used for setting thesensitivity. If the 2020ppbPRO is calibrated with isobutylene, it displays
concentrations in units equivalent to ppm of isobutylene. If isobutylene were the only
photoionizable chemical in the sample, then the 2020ppbPRO would display its
concentration directly.
The 2020ppbPRO responds more or less readily to other chemicals than it does to
isobutylene. Because it has a medium sensitivity to isobutylene, this gas has beenchosen as a reliable means of reporting an average concentration of total ionizable
compounds present.
Gases other than isobutylene can be used to calibrate the 2020ppbPRO. However,
all response factors are based on an isobutylene calibration.

Photoionization Detector
The 2020ppbPRO’s PID is shown in Figure 3. The PID measures the concentrationof photoionizable chemicals in the gas stream from the sample inlet and produces
an electrical signal for the microprocessor.
A UV lamp generates photons which ionize specific molecules in the gas stream.
The permanent air gases (argon, carbon dioxide, nitrogen, oxygen, water vapor,etc.) require a relatively high energy for ionization, and are not ionized by the UV
photons. Many of the compounds considered pollutants, including mosthydrocarbons, are ionized.
The gas stream is directed into the PID through a small port at the center of the UVlamp window and through a series of larger ports around the perimeter of the lamp
window. This arrangement permits a high sample flow rate and short response time.

ionized molecules in the detector cell. An electrometer circuit converts the current toa voltage which is then fed to the microprocessor.
The UV lamp is operated by a high voltage lamp driver circuit which delivers highvoltage energy to the lamp through plates in the lamp holder. The lamp driver power
supply is controlled by the microprocessor based on a feedback signal from a lightsensor on the driver circuit board.

2. Calibration gas containing 10 ppm isobutylene (Part No. MX350025).
Other concentrations of the calibration gas may be required. This will
depend on your application.
3. Zero air (clean dry air without any organic impurities)
There are several alternatives for clean or zero air calibration: you can
use a bottle of clean air (certified as having not more than 0.1 ppm totalhydrocarbons) connected directly to the instrument; the clean air can betransferred to a Tedlar bag which can then be connected to the
instrument; clean, ambient air without detectable contamination; or,ambient air run through the charcoal filter (F1760160).
If you will be using large tanks of gas, specify a single stage, high purity
regulator with a CGA 590 connection at the inlet. The regulator should
also have a 1/8” parallel, compression fitting with which to connect theregulator to the gas bag adapter. The delivery pressure must be
adjustable to between 5 psig (34.5 kPa). You may require a gas bag
and gas bag adapter (Part No. MX380014).

ISP-074-576-P1D

Charging the Battery Pack
NOTE: Only use the AC adapter specified for use with the 2020ppbPRO. Using another AC
adapter will result in damage to the battery pack, the 2020ppbPRO or the adapter
itself.
To charge the battery pack:1. Plug the AC adapter into the jack located on the bottom of the
2020ppbPRO.

2. Plug the AC adapter into an AC outlet. If you are using the European AC
adapter, ensure the correct plug is installed on the line cord . If it is notcorrect for the wall outlet in your area, then it must be replaced.
3. The Charge LED on the 2020ppbPRO indicates the charge state. Red
indicates the battery is being charged. Green indicates the battery is
fully charged and ready for use.
It is normal for a fully charged battery to indicate it is charging (red light)
when first plugged in. The Charge LED will turn green within a few
minutes to indicate the battery is fully charged.
4. When the battery pack is fully charged, remove the AC adapter firstfrom the wall outlet and then from the 2020ppbPRO.

Figure 4. Battery Pack Removal and Replacement
Charging a fully discharged battery pack will take approximately 4 hours.
Optionally you can use the off line charger (Part No. MX350019) to charge thebattery pack when not installed in the 2020ppbPRO.
If you are charging the battery pack in the instrument you can use all the features ofthe 2020ppbPRO while the battery pack is being charged.

ISP-074-576-P1D

39

Leaving the AC adapter connected to the 2020ppbPRO will not harm the battery or
the AC adapter in any way. If the 2020ppbPRO is to be left unused for an extended
period of time, leave it connected to the AC adapter so that the battery will be fully
charged and ready for operation.
On average a fully charged battery pack will provide 6 hours of continuous
operation. Battery life is shorter if the instrument is turned off and then on again
repeatedly, or if the backlighting is turned on.

Sample Intake Conditioner Tube
The 2020ppbPRO is an extremely sensitive instrument designed to measure very
low concentrations of VOCs. The instrument anticipates that the user will bemeasuring VOCs principally in the range of 10ppb to 10ppm, with single ppb
precision.
To achieve this critical sensitivity the instrument utilizes INFICON’s Gas Analysis
System developed in partnership with Dräger Safety AG & Co. All intake to the
instrument is passed through a sample intake conditioner tube (F1760162) which is
attached to the instrument with the INFICON Tube Holder (A1790500).
The tube provides a filtered dry sample which supports stability and precision of
detector response during calibration and sampling.

Display
The 2020ppbPRO has a graphic display for reporting detected concentration and to
guide you through configuration options. All functions of the 2020ppbPRO will bereported on the display.

Graphic Display
The 2020ppbPRO uses an 8 line graphic display. The display will always be used forreporting detected concentration. The 2020ppbPRO will display readings in parts per
billion (ppb) ranging from 10ppb to 40000 ppb with a resolution of 1 ppb.

Fixed Keys
The 2020ppbPRO has two fixed keys. The first fixed key is the ON/OFF key. The
second fixed key is the dedicated calibration key. Pressing the CAL key will start
calibration in almost any mode.
The ON/OFF key is used to both turn power on to the 2020ppbPRO as well as theturn the power off. To turn on the 2020ppbPRO, press the ON/OFF key. To turn the
power off, press the ON/OFF key and hold it down for 5 seconds, and then release
it. This is done to prevent accidental power off.

Soft Keys
The three soft keys on the 2020ppbPRO are located directly below the display. Eachkey has varying functions for configuring the 2020ppbPRO, editing the data, andcontrolling the display. Since only three soft keys are available, each function isbroken down into a path. Maps, showing each path and the resulting functions, areshown in Figures 6, 7, and 8.

Beginning Operation
Turning the 2020ppbPRO On
1. Turn the 2020ppbPRO on by pressing the ON/OFF key. See Figure 1
for the location of the ON/OFF key.
2. The 2020ppbPRO will display the instrument’s software version number.
Next the 2020ppbPRO will proceed to the mode display.
3. The 2020ppbPRO has an instant-on lamp. For maximum accuracy andstability, allow the 2020ppbPRO to warm-up for 10 minutes prior tocalibration.

Operational Displays
When the instrument is turned on the display shows the last mode the 2020ppbPRO
used. The display can show readings either in ppb, ppm, or Mg/M3 units of

Tube Life Time Display
Also, when the instrument is turned on the Tube Life Time status will be displayed in
the lower right portion of the display screen. If the time status is greater than zero,the instrument is ready for use. If the time status is equal to zero, a prompt will be
displayed requesting the user to replace the expired sample intake conditioner tube
with a fresh tube (F1760162) and select the operating range for the instrument (e.g.,High, Medium, or Low depending on ambient humidity).
NOTE: Following the selection of the operating range, the instrument will monitor theamount of time the instrument has been in use and will prompt the user to replace
the tube when the time limit has been reached..

Numeric Value, Duration, Time and Date Entry
In cases where the system requires the user to enter a number, duration, time, ordate, the following mechanism is used. The number of digits to be entered depends
on the type of value being entered. Upon entering a value entry screen, a bar icon
below the left most digit highlights it as the active digit. The up (middle soft button)and down (left soft button) arrows are used to increase/ decrease the digit. The bar
icon is moved to the next digit to the right using the right soft button. Once the user
has finished entering the value they use the right soft button to move the bar icon to
the far right to highlight the check mark. When the bar is under the check mark, theleft soft button changes to ‘done’. The user is then able to input the value. Pressing
the right soft button while the check mark is highlighted will return the bar icon to theleft most digit.
In some cases, units may be specified (e.g., ppm or hh:mm); in others there may be
no units.
No cancel option is available to the user. A value must be input.

System Alerts and Alarms
While operating the instrument, system alerts can occur. To accurately identify thesource of the alarm, each type of alarm has been given a unique status.
In addition to the status, the 2020ppbPRO also has an audio alarm and an alarm
LED. To conserve power, the 2020ppbPRO alternates between the LED and audio.
Different alarms are identified by the frequency at which the 2020ppbPRO alternates
between the audio and LED; Peak alarm is 5 times per second, STEL alarm is 2.5
times per second, and TWA alarm is 1.25 times per second.

46 46

ISP-074-576-P1D

A soft key is used for acknowledging alarms and is named “Accept”. If no alarm
exists, then the “Accept” key is not shown. To clear the alarm, press the “Accept”
key. Once acknowledged, the alarm indicators are cleared. The alarm status willremain until the alarm condition clears.
The 2020ppbPRO updates the instantaneous concentration once every second.
Following every update, the instantaneous concentration is compared to the peakalarm level, and if exceeded, an alarm is triggered.
In Interval mode, if a 15-minute average exceeds the STEL, a STEL alarm isgenerated. The TWA alarm is generated when the current average ofconcentration, since the TWA was last cleared, has exceeded the TWA exposure
limit.
During calibration, all alarms are disabled. Once the calibration is complete, thealarms are re-enabled.

User Interface – Basic Menu
The 2020ppbPRO is designed for ease of use with a logically organized internalmenu structure/user interface. The 2020ppbPRO User Menu is shown in Figures 6,7, and 8.
The 2020ppbPRO has three soft keys under the graphic LCD display which always
show the available functions of the soft keys in any screen.

Operation Modes
Logging Off Mode
Logging Off mode is identified by the word “LOG” with a diagonal line through theword “LOG” in the upper right corner of the 2020ppbPRO display. Logging Off willcontinuously display the concentration of total volatile compounds present that the
2020ppbPRO can ionize. The reading is updated approximately once per second. In
Logging Off mode, the only soft key displayed is MENU.
MENU selects the 2020ppbPRO’s internal menu for the instrument setup by theuser.

Tag Mode
Tag mode is identified by the word “TAG” in the upper right-hand corner of the
2020ppbPRO display. Tag mode will continuously display the instantaneousconcentration of total volatile compounds. Tag mode also allows the user tomanually tag and datalog readings. Tag mode allows the user to datalog abackground reading, a sample reading and assign Site Codes to readings. Site
Codes are set using the 2020ppbPRO Comm software. See Chapter 4, Connecting
Accessories, for more information on how to use the 2020ppbPRO Comm software.
In Tag mode, the soft keys are VIEW, TAG and MENU.

ISP-074-576-P1D

VIEW selects datalogger review.
TAG selects “No Label”, “Background”, or “Sample”.
MENU selects the 2020ppbPRO’s internal menu for the 2020ppbPRO setup by theuser.

Interval Mode
Interval displays the instantaneous readings as well as STEL, TWA, and PEAK
readings. Interval mode is identified by the letters “INT” in the upper right-handcorner of the 2020ppbPRO display. Interval automatically calculates and updates
STEL, TWA, and PEAK readings. Interval mode also automatically stores thesereadings in the 2020ppbPRO’s memory at a preset interval selected by the user. In
Interval mode, the soft keys are VIEW, CLEAR and MENU.
VIEW selects datalogger review.
CLEAR selects clearing the values for “TWA”, “PEAK”, “ALL”.
MENU selects the2020ppbPRO’s internal menu for the 2020ppbPRO setup
by the user.

Short-Term Exposure Limit (STEL) Mode
The Short-Term Exposure Limit (STEL) mode displays the concentration as a 15minute moving average. The 2020ppbPRO maintains 15 samples, each
representing a one-minute averaging interval.
Once every minute, the oldest of the 15 samples is replaced with a new one-minute
average. This moving average provides a 15-minute average of the last 15 minuteswith a one-minute update rate. Since the average is calculated using 15 one-minute
averages, the meter display will only update once every minute.
STEL is set to zero each time the instrument is turned on. Since STEL is a 15minute moving average, there is no need to clear or reset the STEL.
STEL calculations are always being performed by the 2020ppbPRO. You candisplay the results of the calculations by selecting Interval Mode.

Time-Weighted Average (TWA) Mode
The TWA accumulator sums concentrations every second until 8 hours of data havebeen combined. If this value exceeds the TWA alarm setting, a TWA alarm isgenerated. The TWA is not calculated using a moving average. Once 8 hours ofdata have been summed, the accumulation stops. In order to reset the TWA
accumulator, press the “Clear” key, then select “TWA” using the “Down Arrow” key,then press “Clear”.
This sum will only be complete after 8 hours, so the meter displays the current sum
divided by 8 hours.
TWA calculations are always being performed by the 2020ppbPRO. You can display
the results of the calculations by selecting Interval mode.

ISP-074-576-P1D

PEAK Mode
The PEAK mode displays the current detected concentration. The reading is
updated once a second. In the background, the 2020ppbPRO datalogger issampling the concentration and measuring minimum, maximum, and average
concentrations for the selected averaging interval. At the end of every interval, one
entry is placed in the datalogger until the datalogger is full.
In order to reset the PEAK reading, press the “Clear” key then select “PEAK” using
the “Down Arrow” key then press “Clear”.

Datalogger
Interval Operation
The microprocessor accumulates all readings in an averaging interval that you
select, and determines the minimum, average and maximum readings. It stores
these numbers along with the highest priority instrument status and the most recent
time and date.
These recorded data can now be reviewed and edited. Recorded data can also be
printed using the PC. For each averaging interval, the 2020ppbPRO prints theminimum of all the minima, the average of all the readings for the interval and the
maximum of all the maxima.
In PEAK mode, the reading is updated once a second. In the background, the2020ppbPRO datalogger is sampling the concentration and measuring min, max,
and average concentrations for the selected averaging interval. At the end of every
interval, one entry is placed in the datalogger until the datalogger is full.
In STEL mode, 15 samples are combined to form a 15-minute average. Once every
minute, the oldest of the 15 samples is replaced with a new one-minute average.
This moving average provides a 15-minute average with a one-minute update rate
so the meter display will only update once every minute. STEL is set to zero eachtime the instrument is turned on.
STEL calculations are always being performed by the 2020ppbPRO. You candisplay the results of the calculations by selecting STEL as the Display mode.
TWA mode sums concentrations every second until 8 hours of data have been
accumulated. Once 8 hours of data have been summed, the accumulation stops.
This sum will only be complete after 8 hours, so the meter displays the current sum
divided by 8 hours. While you are in TWA mode, the time on the status display willshow the number of minutes and hours of data that TWA has accumulated. When
this reaches 8 hours, the 2020ppbPRO stops accumulating data and the TWA iscomplete.
TWA calculations are always being performed by the 2020ppbPRO. You can display
the results of the calculations by selecting TWA as the Display mode.
Interval mode logs readings at user-selected intervals of 1 second to 999 seconds.

Response Factor Library
The response of a PID to a compound is dependent on its ionization potential. In
certain situations when the user is confident that only a single specific compound
exists, they can set up the 2020ppbPRO using an isobutylene calibration to mimicthe 2020ppbPRO response as if the 2020ppbPRO was calibrated using that specificsingle compound.

General Information
In situations where only a single pure compound is present in air, the 2020ppbPRO
should be calibrated with a standard of that specific compound as span gas. The
2020ppbPRO’s 15 memory slots can be used to store calibration information for 15
different span gases.
The 2020ppbPRO will always detect all ionizable compounds present in a sample
regardless of the response factor (RF) selected.
NOTE: Even if the 2020ppbPRO has been calibrated with a specific compound, its
response is not specific and the presence of another ionizable impurity may render
the numerical result invalid.
It is often impractical to carry a range of different standards into the field.
Approximate results can be obtained by calibrating the 2020ppbPRO with therecommended span gas and entering the appropriate response factor. The
response factor is based on the ratio of the response of the specific compound to
the response of the span gas. The response factor multiplies the 2020ppbPRO’s
reading, then displays and records it.

56 56

ISP-074-576-P1D

The 2020ppbPRO is a total VOC instrument and will ALWAYS respondto all ionizable compounds present in a sample. The 2020ppbPRO will
NEVER respond only to a specific compound if an RF is programmed.
It is the responsibility of the user to be aware of the limitations of PID
instruments.

Calibration Technical Description
Periodic calibration is required to compensate for the 2020ppbPRO output changes
due to inlet filter restriction, ionization chamber contamination, lamp cleanliness,pump wear and other factors.
During calibration, the 2020ppbPRO is first exposed to zero air. A small (zero) signal
is generated. This zero signal is stored by the microprocessor.
The 2020ppbPRO is next exposed to span gas. This span gas signal is stored by
the microprocessor. The microprocessor subtracts the zero signal from the span gas
signal and divides the difference by the user-entered span gas concentration. The
resulting sensitivity is stored in the selected Memory Slots with the zero signal andthe alarm levels. This number is then multiplied by the response factor anddisplayed.
The 2020ppbPRO readings are always relative to the calibration gas. Aftercalibration with isobutylene, the 2020ppbPRO will respond directly in units
equivalent to isobutylene. Most volatile organic compounds will be detected by the
2020ppbPRO. It cannot distinguish between isobutylene and other ionizable
compounds. A reading of 10 ppm indicates all ionizable compounds that are present
have generated an ion current proportional to 10 ppm of isobutylene. The reading is
actually 10 ppm isobutylene equivalent units. The 2020ppbPRO readings give an
indication of the total ionizables present and their concentration relative to thecalibration gas.

Calibration Introduction
The 2020ppbPRO must be calibrated in order to display concentration in ppm units
equivalent to the calibration gas. First, zero air, which should not contain any
ionizable gases or vapors, is used to set the 2020ppbPRO’s zero point. Then, acalibration gas, containing a known concentration of a photoionizable gas or vapor,
is used to set the sensitivity.
Due to the 2020ppbPRO’s sensitivity, outdoor air is usually unsuitable for calibration
unless the intake sample conditioner tube (F1760162) and filter tube holder(A1790500) is used.

NOTE: Ultra Zero air (99.999 % free of VOCs) may also be used for zero calibration in
combination with the intake sample conditioner tube (F1760162) and filter tube
holder (A1790500).
The same tube should be used for conditioning the calibration gas. Once calibration
is done, the tube is discarded and a new tube is used for sampling purposes.
If compound threshold limit values (TLVs) are exceeded, you should use a gas bag
for sampling and calibration.
To determine the TLV of the compounds contained in the calibration gas, refer to theMaterial Safety Data Sheet (MSDS) supplied with your calibration gas cylinder.
If you will be using a gas bag for span gas calibration, see Calibration Using a Gas
Bag on page 63 for instructions.
NOTE: Disconnect the 2020ppbPRO from the AC adapter before beginning calibration.

Compressed Gases
Cylinders of compressed gas, such as calibration gas, must be handled withextreme care. For safety, the calibration gas cylinders must be secured before use.
Please observe the following handling procedures:

60 60



Mark each new regulator with its intended gas service and never use a regulator
for more than one service. To ensure safety and avoid contamination, regulators
should be dedicated to one service. Do not change gas service or adapt
equipment without consulting your gas supplier.



Do not heat or expose cylinders or regulators to temperatures above 52°C
(125°F). The cylinders may rupture at high temperatures.

Use only the specified regulator for the calibration gas. Confirm regulator typeand material with your specialty gas supplier.



Always secure cylinders before removing the cylinder valve protection cap.

Do not drag or roll cylinders. Large cylinders should only be moved on carts
designed for compressed gas cylinders. Do not move cylinders without the valve
protection cap in place.



Wear safety glasses when working with compressed gases.



Do not store cylinders in a hazardous location. Store cylinders in an uprightposition away from possible sources of heat or sparks.



Never plug, obstruct or tamper with safety relief devices.

ISP-074-576-P1D

Regulators for Compressed Gases
When connecting a regulator to a large cylinder:Ensure cylinder valve and regulator connection match.

Ensure regulator construction materials are compatible with the gas, and thatthe cylinder pressure gauge will withstand the cylinder pressure.



Never use the regulator as a shut-off valve. Close the cylinder when it is not inuse.

Do not subject the regulator to an inlet pressure greater than recommended.

Do not move or detach the regulator when it is pressurized or when it is in use.



Before connection, ensure the gas cylinder valve and the regulator CGA
connection are clean.



Turn the pressure control valve on the cylinder all the way off (close thecylinder). Turn the regulator outlet to off. Open the gas cylinder valve slowly andcheck for leaks. Adjust the delivery pressure and then open the regulator outlet
valve.

Calibration Gas
Adequate ventilation must be provided when the 2020ppbPRO is being calibrated.
If compound threshold limit values (TLV) are exceeded, you should use a gas bag
for sampling and calibration.
To determine the TLV of the compounds contained in the calibration gas, refer to theMaterial Safety Data Sheet (MSDS) supplied with your calibration gas cylinder. See
Calibration Using a Gas Bag on page 63 for more details.

11.7 eV UV Lamp
General Information
The 2020ppbPRO is equipped with the standard 10.6 eV high performance UV
lamp. An optional 11.7 eV UV lamp (Part No. MX390024) is available for special
applications.
Install this lamp as outlined in Removing and Replacing the UV Lamp on page 77.
When you install a UV lamp other than the 10.6 eV high performance UV lamp, all
the response factors become invalid. You must set the response factor for thecurrent cal memory to 1. Contact INFICON’s Applications Department for further
information.

Limitations of Lithium Fluoride Lamp Window
This lamp is intended for special applications only. It is not suitable for normal
operation, due to limitations of the lamp window material.
The 11.7 eV lamp window material is lithium fluoride (LiF). LiF is composed of twolight elements which are easily disrupted within the crystal lattice by the UV light
generated by the lamp. This process is called solarization and it is evidenced by the
crystal gradually becoming opaque. Lamp performance declines as this happens.

ISP-074-576-P1D

71

Also, unlike other UV lamp windows, LiF readily absorbs water from atmospherichumidity. When contaminated by moisture, the window loses its ability to transmit
UV light.
NOTE: Do not touch the lamp window or handle it near water.

Using the 11.7 eV UV Lamp
With an 11.7 eV lamp installed, your instrument functions as a detector responding
to compounds which ionize at 11.7 eV or less. The 11.7 eV lamp may be useful for
detecting compounds not ionized by the standard 10.6 eV lamp.
Due to the lamp window limitations, the lifetime of the 11.7 eV lamp is restricted andit must be used sparingly according to the following instructions.

To use the 11.7 eV lamp in your the 2020ppbPRO:

1. Remove the 11.7 eV lamp from the supplied desiccant bottle and install
the lamp as outlined in Removing and Replacing the UV Lamp on page 7.
NOTE:

Do not remove or replace any detector lamp in a hazardous location.

2. Turn the instrument on and wait for the ready status. If the lamp cannot
be started, contact INFICON’s Technical Support Department.

3. Calibrate the 2020ppbPRO. See Calibration Using the Flow-Match
Regulator on page 61.

4. All response factors are invalid when an 11.7 eV lamp is installed. The
response factor must be set to 1.

5. Every hour of operation, switch off the instrument, remove the lamp andexamine the window for yellowing. If the window is yellow, thenregenerate the window according to the procedure in

6. Cleaning the Lithium Fluoride Window on page 80.
7. After use, remove the lamp and store it in the supplied desiccant bottle.
Do not leave the 11.7 eV lamp in the instrument when you turn it off. Always remove
the 11.7 eV lamp and store it in the supplied desiccant bottle.

Battery Charging
A fully charged battery pack powers the 2020ppbPRO for approximately 8 hours. If
the instrument is to be used for more than 8 hours, carry a spare battery pack (PartNo. MX700010 or MX700011). When the first one has been discharged, replace itwith the spare.
NOTE: If you do not turn the 2020ppbPRO off before removing the battery pack, you will
reset the instrument and you will lose all logged data and setup parameters.
When the 2020ppbPRO displays the low battery symbol, the battery pack requires
charging. When the low battery symbol is displayed, you have 30 minutes ofoperation left. The 2020ppbPRO will turn itself off before the battery pack becomes
critically low.

Do not remove or recharge the battery pack in a hazardous location.

WARNING
Upon return from field work, charge the battery packs as outlined in Battery
Charging on page 39. Use only the AC adapter specified for use with the2020ppbPRO. Optionally you can use the off-line charger to charge the battery packindependently of the instrument. See Off-Line Charger on page 73.
NOTE: You must use the 220 V battery charger (Part No. MX396013) in order to comply
with the requirements of the applicable Council Directives.
If you do not require portable operation, you can use the 2020ppbPRO while it isconnected to the AC adapter.

The 2020ppbPRO is not intrinsically safe when connected to an AC adapter.

WARNING
The AC adapter automatically charges at a high charge rate until the battery pack isfully charged. It then maintains the full charge with a low continuous charge rateindefinitely so there is no danger of over-charging.

When the Charge LED on the top of the 2020ppbPRO is red, the battery is charging.
When the Charge LED turns green, the battery is fully charged.

Battery Pack Care
Leaving the 2020ppbPRO for more than 3 months without charging the batteries
may result in the loss of recorded data and setup parameters. If the 2020ppbPRO is
not used for long periods of time, recharge the battery for a few hours every 30 days

76 76

ISP-074-576-P1D

Maintenance of the UV Lamp
Removing and Replacing the UV Lamp
NOTE: Do not remove or replace the UV lamp in a hazardous location.
To remove the UV lamp from your instrument:
1. Ensure the instrument is turned off.

You must turn the instrument off before removing the lamp cover.

WARNING
2. Remove the lamp housing cover.
3. Tilt the 2020ppbPRO slightly and remove the UV lamp.

Do not touch the wire grid inside the detector cell. Any dust or dirt in thedetector cell can be blown out with a gentle jet of compressed air.
Do not insert any object, other than the UV lamp, into the lamp holder.
WARNING
4. Without touching the lamp window, place the new lamp into the2020ppbPRO lamp holder, window first. See Figure 21.

ISP-074-576-P1D

77

Figure 21. Removing the UV Lamp
NOTE: Do not force the lamp into the lamp holder.
5. Replace the lamp housing cover. Tighten the cover down. Do not overtighten.
6. Calibrate the 2020ppbPRO and then continue normal operation.

Cleaning the UV Lamp Window
During the course of normal operation, a film builds up on the window of the UV
lamp. The rate at which the film develops depends on the type and concentration of
the gases and vapors being sampled and results from the UV light interacting withthem.
Hot gases and vapors may contribute to a decrease in sensitivity because they may
condense on the lamp window. Condensation may eventually evaporate off thewindow, but it will usually leave a residue that must be removed by cleaning thelamp window.
Since some UV inhibiting deposits are invisible to the eye, regular cleaning of thelamp window is strongly recommended. Clean the lamp frequently to prevent aheavy buildup of deposits that may be difficult to remove.

Do not remove the UV lamp in a hazardous location.

WARNING

78 78

ISP-074-576-P1D

The UV lamp cleaning kit (Part No. MX380336) includes aluminum oxide powder(3.0-micron powder) and cotton swabs. Additionally, you will require approximately
10 mL of methanol. When ordering methanol, specify purge and trap grade.
The instructions provided below are for 10.6 eV lamps. Refer to
Cleaning the Lithium Fluoride Window for special instructions to clean the 11.7 eVlamp window.

Never touch the UV lamp window with your fingers.

WARNINGTo clean the UV lamp:
1. Remove the lamp as outlined in Removing and Replacing the UV Lamp on
page 77.
2. Allow the lamp to cool to room temperature to avoid thermal shock,which could crack the window.
3. Dampen a cotton swab in methanol and dab it into the cleaning
compound. Allow a small amount of the cleaning compound to adhere
to the cotton tip.

Do not use methanol to clean the 11.7 eV lamp window.

WARNING
4. Using small circular motions, rub the cleaning compound onto the lamp
window. Do not exert excessive force onto the window, since thewindow can be permanently damaged by misuse.
5. Continue cleaning for approximately one minute.
6. Dampen a new cotton swab with methanol and remove any trace
amounts of the cleaning compound from the lamp window.
7. Wipe the window and the lamp with a dry, lint free tissue to remove any
trace amounts of the cleaning compound and methanol. All traces ofcleaning compound must be removed.
8. If you removed an O-ring from the lamp, replace it now. Ensure yourhands are clean and dry.

Cleaning the Lithium Fluoride Window
To clean the 11.7 eV lamp window:
1. Clean the lamp window with dry aluminum oxide powder on a dry cottonswab. Do not use methanol or water.
2. Wipe the window and the lamp with a dry, lint free tissue to remove any
trace amounts of the cleaning compound and methanol. All traces ofcleaning compound must be removed.
NOTE: You may not be able to fully clean the 11.7 eV lamp window. The solarizaton effectcannot be cleaned and will require replacement of the lamp (anticipated life is 1 - 3months depending on amount of use).

Replacing the Sample Inlet Filter
The 2020ppbPRO is equipped with a combined dust and water filter to reduce
detector contamination. As the filter collects dust, the 2020ppbPRO’s inlet flow rateand sensitivity decrease. The filter will not allow water to pass through, but the filter
will not stop all solvents.
NOTE: Do not aspirate liquid samples with the 2020ppbPRO!
Replace the filter on a weekly basis, or more frequently if the 2020ppbPRO is used
in a dusty or wet environment. You must replace the filter if the 2020ppbPRO has
been exposed to water. If you are sampling hot gases or vapors, condensation in
the sample line may also affect the filter.
Do not replace the inlet filter in a hazardous location.

WARNINGTo replace the inlet filter:
1. Turn the instrument off. Unscrew the filter housing from the detector
housing. Be careful not to lose the O-ring seal.
2. Remove the Teflon/Polypropylene filter and install the new filter (PartNo. MX750100). Place the filter so that the Teflon side is facing down in
the filter housing and the mesh side is facing the 2020ppbPRO.

AC wall outlet in your area. If this cannot be done, you may need to obtain an ACline cord suitable for the AC receptacle in your area.
The AC line cord, attached plug and receptacle must be marked with your country’s
certification mark and the cord must have a Harmonization (HAR) mark.
The line cord must be rated for either 100 to 120 VAC at 60 Hz or 220 to 240 VAC at
50 Hz. The voltage rating will depend on the voltage in your area.
Contact your INFICON representative to obtain more information.

Calibration Gas Supplier
The recommended span gas is isobutylene in air. 100 ppm isobutylene in air may beobtained from INFICON.
The exact concentration will be determined by your application. Other
concentrations and other gases may be obtained from your local gas supplier. If you
cannot locate a local gas supplier, contact INFICON’s Technical Support
Department.

Using the Gas Bag
To fill gas bag:
1. Turn the knurled plastic knob counter clockwise to unlock it. Use theknurled collar on the valve tube to gently push the valve tube down,
toward the bag.
2. Turn the knurled plastic knob clockwise to lock the valve tube in place.
3. Turn the regulator knob counter clockwise about half a turn to start theflow of gas. Fill the gas bag about half full and then close the regulator.
4. Open the syringe port and empty the bag. Flush the bag a few times
with the calibration gas and then fill it.
5. To close the gas bag valve, turn the knurled plastic knob counterclockwise to unlock it. Gently pull the valve tube up to close the valve.
Turn the knurled plastic knob clockwise to tighten it against the valve
tube.
Once the bag has been filled, use the bag and sample as soon as possible.
NOTE: Do not use gas bags to sample unstable or highly reactive compounds. Do not use
Tedlar® bags for storage of hazardous materials.

Replacing the Septum
Remove retainer andreplace silicone septum.
Place septum with
Teflon side down.

Replace septum after
5-10 injections.To replace
septum, turn retainer counterclockwise. For replacement
septa order Teflon bonded to
Silcone, diameter = .375" (9.5 mm)

Replace retainer
Do not overtighten.
Overtightening may resultin needle blocakge

Presets and Response Factors
Presets simplify Memory Slot programming, and provide standard response factors
and alarm levels for approximately 100 compounds. The name, response factor andthree alarm levels are all set from the preset.
You can change any of the values entered in the Memory Slots. Changes made to
the library information that has been loaded into a Preset will have no effect on theoriginal library entry.
The response factors were determined over the range 5 - 500 ppm, based on a 100ppm isobutylene calibration. Isobutylene RF = 1.0. The following formula is used for
calculation of response factors:

Response Factor =Actual Concentration
2020ppbPRO Response

A response factor less than 1.0 indicates a compound response better than that ofisobutylene. A response factor greater than 1.0 indicates a lower response than thatof isobutylene.
NOTE: It does not matter which response factor is entered. The 2020ppbPRO’s response is
not specific to any one compound. The displayed reading represents the total
concentration of all ionizable compounds in the sample.
