INFICON 2020ppbPRO User Manual

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 to assist in the early detection of hazardous conditions involving such compounds.

It is vitally important to ensure that the 2020ppbPRO is maintained in accordance with INFICON’s instructions and that proper calibration is regularly 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 the user 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 that can be ionized by a photoionization detector. The 2020ppbPRO automatically displays and can record these concentrations. The 2020ppbPRO does not distinguish 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 Interval mode, these values are automatically recorded in the 2020ppbPRO’s memory. The 2020ppbPRO can log up to 12,000 entries.

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 the presence 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 and records the signal generated by the photoionization detector (PID). Recorded data and setup information entered into the microprocessor’s memory are retained when the 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 an electrical signal. The microprocessor subtracts any background from the signal and divides this signal by a sensitivity obtained by calibrating with a standard gas of known 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 and vapors and its response depends on the characteristics as well as the concentration of 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.

A standard of isobutylene at a known concentration may be used for setting the sensitivity. 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 been chosen 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 concentration of 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 most hydrocarbons, are ionized.

The gas stream is directed into the PID through a small port at the center of the UV lamp 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.

Figure 3. Photoionization Detector

The ionized molecules in the detector cell are subjected to a continuous electric field between the repeller electrode and the collector electrode. The ions move in the electric field, generating a current which is proportional to the concentration of the

34 ISP-074-576-P1D

ionized molecules in the detector cell. An electrometer circuit converts the current to a voltage which is then fed to the microprocessor.

The UV lamp is operated by a high voltage lamp driver circuit which delivers high voltage 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 light sensor on the driver circuit board.

Unpacking Instrument

Remove the 2020ppbPRO from its shipping box. The following accessories are included with the 2020ppbPRO:

1. Sample Probe

2. Instrument Manual (on CD)

3. Multi-Tool

4. AC Adapter or AC Adapter with AC Line Cord

5. Replacement Sample Inlet Filters (10 pieces)

6. Reference Card

7. Water-trap Filter

8. INFICON filter tube holder

9. Intake sample conditioner tubes

Ensure that all of these accessories have been included with the instrument. If any items are missing or damaged, contact INFICON immediately.

Support Equipment and Consumables Calibration

For normal operation these items are required:

1. Calibration Gas Regulator (Part No. MX350006).

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 total hydrocarbons) connected directly to the instrument; the clean air can be transferred 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 the

regulator 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 35

4. 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 the Material Safety Data Sheet (MSDS) supplied with your calibration gas cylinder.

If you will be using a gas bag for calibration, see Calibration Using a

Gas Bag on page 63 for instructions.

Battery Charging

Before beginning operation of the 2020ppbPRO, the battery pack must be charged. You can also remove the battery pack and replace it with a fully charged spare battery pack (Part No. MX700010 or MX700011).

NOTE: You must use the 220 V battery charger (Part No. MX396013) in order to comply

with the requirements of the applicable Council Directives.

Removing and Replacing the Battery Pack

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

To remove the battery pack:

1. If the 2020ppbPRO has been turned on, turn it off by pressing the

ON/OFF key for five seconds and then releasing it.

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.

2. Locate the battery hatch on the back of the instrument. See Figure 4.

3. Loosen the two Phillips screws in the top of the battery hatch.

4. The battery hatch can now be removed.

5. Lift the battery pack out of the case and carefully disconnect the battery

pack connector from the 2020ppbPRO.

6. Attach the connector from the charged battery pack to the

2020ppbPRO.

NOTE: The connector is polarized. It will only fit one way. Do not force the connection.

7. Place the battery pack in the 2020ppbPRO case. Ensure the battery

wires are not pinched or strained.

8. Ensure the wrist strap ring is in proper position. This ring holds the wrist

strap in place.

9. Replace the battery hatch and then replace the two screws. Do not

over-tighten the screws as you will damage the case.

38 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 not correct 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 first

from 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 the

battery pack when not installed in the 2020ppbPRO. If you are charging the battery pack in the instrument you can use all the features of

the 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 be measuring 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 be reported on the display.

Graphic Display

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

40 ISP-074-576-P1D

Figure 5. The 2020ppbPRO Display

The display reports instantaneous concentration at all times when the pump is on. In Interval mode, the display will report instantaneous concentrations as well as PEAK, STEL or TWA.

The 2020ppbPRO is designed for ease of use with a logically organized internal menu 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.

Keys 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 the turn 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. Each key has varying functions for configuring the 2020ppbPRO, editing the data, and controlling the display. Since only three soft keys are available, each function is broken down into a path. Maps, showing each path and the resulting functions, are shown 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 and

stability, allow the 2020ppbPRO to warm-up for 10 minutes prior to calibration.

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

ISP-074-576-P1D 43

measure. The resolution is 10ppb. The meter will display concentrations from 10 ppb up to 40,000 ppb.

The 2020ppbPRO can power up in Logging Off, Tag, or Interval mode depending on the mode that was set by the previous user. The current mode is shown in the upper right-hand corner of the display.

Figure 9. Logging Off Mode Display

Figure 10. Tag Mode Display

44 ISP-074-576-P1D

Figure 11. Interval Mode Display

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 the

amount 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, or date, 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, the left 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 the left 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.

Instrument Status

The instrument status is shown on the left of the first line of the status display. Each status has a priority assigned to it. If more than one status is in effect, then the status with the highest priority is displayed until the condition is corrected or until the option is turned off. Table 1 is a list of the possible system alerts.

Table 1. System Alerts

System Alerts and Alarms

While operating the instrument, system alerts can occur. To accurately identify the source 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 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 will remain until the alarm condition clears.

The 2020ppbPRO updates the instantaneous concentration once every second. Following every update, the instantaneous concentration is compared to the peak alarm level, and if exceeded, an alarm is triggered.

In Interval mode, if a 15-minute average exceeds the STEL, a STEL alarm is generated. The TWA alarm is generated when the current average of concentration, since the TWA was last cleared, has exceeded the TWA exposure limit.

During calibration, all alarms are disabled. Once the calibration is complete, the alarms are re-enabled.

User Interface – Basic Menu

The 2020ppbPRO is designed for ease of use with a logically organized internal menu 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 the word “LOG” in the upper right corner of the 2020ppbPRO display. Logging Off will

continuously 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 the user.

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 instantaneous concentration of total volatile compounds. Tag mode also allows the user to manually tag and datalog readings. Tag mode allows the user to datalog a background 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 47

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

user.

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-hand corner of the 2020ppbPRO display. Interval automatically calculates and updates STEL, TWA, and PEAK readings. Interval mode also automatically stores these readings 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 minutes with 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 can display 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 have been combined. If this value exceeds the TWA alarm setting, a TWA alarm is generated. The TWA is not calculated using a moving average. Once 8 hours of data 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.

48 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 is sampling 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 the minimum 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, the 2020ppbPRO 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 each time the instrument is turned on.

STEL calculations are always being performed by the 2020ppbPRO. You can display 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 will show 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 is complete.

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.

On selecting Units from the MENU, the three choices will appear as a list. Using the center soft key, highlight the desired Units of Measure and use the SELECT soft key to set the choice.

NOTE: To utilize the mg/M3 unit of measure, the instrument must be configured and

operated with a compound chosen from the 2020ppbPRO’s Preset RF library because a molecular weight value is needed for the mg/M3 calculation. If you wish to use the mg/M3 unit of measure while doing TVOC work, you should use a memory slot with Isobutylene selected from the Preset RF library. Refer to Section: Response Factors and Memory Slots for further information.

Sample Collection Mode

The 2020ppbPRO can be used to collect samples for further analysis at another location with another instrument (e.g., back at a laboratory using a GC). Sample collection is conducted utilizing the optional INFICON Tube Holder (A1790500) and sample collection tubes. On selection of SAMPLE MODE from the UNIT SET UP menu, the pump will shut off and the user will be instructed to attach the TUBE HOLDER and fresh SAMPLE TUBE. The SAMPLE soft key will activate the pump for a short period of time drawing ambient air into the SAMPLE TUBE. When finished, the user will be prompted to either continue sampling or return the 2020ppbPRO to normal operating mode.

ISP-074-576-P1D 55

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 mimic the 2020ppbPRO response as if the 2020ppbPRO was calibrated using that specific single 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 the recommended 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 ISP-074-576-P1D

WARNING

The 2020ppbPRO is a total VOC instrument and will ALWAYS respond to 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.

Response Factors and Memory Slots

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 and the alarm levels. This number is then multiplied by the response factor and displayed.

The 2020ppbPRO readings are always relative to the calibration gas. After calibration 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 the calibration gas.

2020ppbPRO

ISP-074-576-P1D 59

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, a calibration 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 the Material 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 with extreme care. For safety, the calibration gas cylinders must be secured before use. Please observe the following handling procedures:

 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 type

and 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 upright

position away from possible sources of heat or sparks.

 Never plug, obstruct or tamper with safety relief devices.

60 ISP-074-576-P1D

Regulators for Compressed Gases

WARNING

Observe proper handling procedure for all 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 that

the cylinder pressure gauge will withstand the cylinder pressure.

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

use.

 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 the

cylinder). Turn the regulator outlet to off. Open the gas cylinder valve slowly and check 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 the Material 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 the current 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 two light 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 atmospheric humidity. 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 and it 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 and

examine the window for yellowing. If the window is yellow, then regenerate 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.

WARNING

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

WARNING

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

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 (Part No. MX700010 or MX700011). When the first one has been discharged, replace it with 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 of operation left. The 2020ppbPRO will turn itself off before the battery pack becomes critically low.

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 the 2020ppbPRO. Optionally you can use the off-line charger to charge the battery pack independently 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 is connected to the AC adapter.

The AC adapter automatically charges at a high charge rate until the battery pack is fully charged. It then maintains the full charge with a low continuous charge rate indefinitely 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

76 ISP-074-576-P1D

not used for long periods of time, recharge the battery for a few hours every 30 days

to avoid loss of data. See Battery Charging on page 38 for instructions on charging

conducting materials such as rings, bracelets and keys. The battery or conductor may overheat and cause burns.

 Charge the battery pack using the AC adapter provided with or identified for use

with this product only in accordance with the instructions and limitations specified in this manual. For AC adapter use only Part No. MX350002 (North America) or MX396013 (Europe).

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.

2. Remove the lamp housing cover.

3. Tilt the 2020ppbPRO slightly and remove the UV lamp.

4. Without touching the lamp window, place the new lamp into the

ISP-074-576-P1D 77

2020ppbPRO lamp holder, window first. See Figure 21.

WARNING

Do not remove the UV lamp in a hazardous location.

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 over

tighten.

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 with them.

Hot gases and vapors may contribute to a decrease in sensitivity because they may condense on the lamp window. Condensation may eventually evaporate off the window, but it will usually leave a residue that must be removed by cleaning the lamp window.

Since some UV inhibiting deposits are invisible to the eye, regular cleaning of the lamp window is strongly recommended. Clean the lamp frequently to prevent a heavy buildup of deposits that may be difficult to remove.

78 ISP-074-576-P1D

The UV lamp cleaning kit (Part No. MX380336) includes aluminum oxide powder

WARNING

Never touch the UV lamp window with your fingers.

WARNING

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

(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 eV

lamp window.

To 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.

4. Using small circular motions, rub the cleaning compound onto the lamp

window. Do not exert excessive force onto the window, since the window 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 of cleaning compound must be removed.

8. If you removed an O-ring from the lamp, replace it now. Ensure your

hands are clean and dry.

9. Without touching the lamp window, replace the lamp as outlined in

ISP-074-576-P1D 79

Removing and Replacing the UV Lamp on page 77.

WARNING

Do not replace the inlet filter in a hazardous location.

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 cotton

swab. 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 of cleaning compound must be removed.

NOTE: You may not be able to fully clean the 11.7 eV lamp window. The solarizaton effect

cannot be cleaned and will require replacement of the lamp (anticipated life is 1 - 3 months 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 rate and 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.

To 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 (Part

No. MX750100). Place the filter so that the Teflon side is facing down in the filter housing and the mesh side is facing the 2020ppbPRO.

Installing Alternate AC Plug on the Battery Charger

In most cases the 2020ppbPRO will be shipped with an AC line cord that will fit the AC wall outlet in your area. If this cannot be done, you may need to obtain an AC line 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 be obtained 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 the knurled 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 the flow 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.

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 and three 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 the original 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:

A response factor less than 1.0 indicates a compound response better than that of isobutylene. A response factor greater than 1.0 indicates a lower response than that

NOTE: It does not matter which response factor is entered. The 2020ppbPRO’s response is
