2020ComboPRO Overview

Figure 1. The 2020ComboPRO Instrument

The 2020ComboPRO measures the concentration of airborne gases and vapors that can be ionized by a photoionization detector. The 2020ComboPRO automatically displays and can record, these concentrations. In TVOC mode, the 2020ComboPRO does not distinguish between individual compounds. The reading displayed represents the total concentration of all photoionizable chemicals present in the sample. In GAS mode, 2020ComboPRO is able to measure benzene when the benzene pre-filter tube holder and benzene pre-filter tube are installed.

The 2020ComboPRO display updates itself once per second. You can read concentrations directly from the display. The 2020ComboPRO is factory-set to display concentration in units of ppm, and concentrations can be displayed in ppb or mg/m3.

The 2020ComboPRO 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 2020ComboPRO 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 memory of the 2020ComboPRO. The 2020ComboPRO can log up to 12,000 entries.

In Tag mode operation, the 2020ComboPRO prompts you to locate a site and then to record 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 2020ComboPRO has 5 keys for instrument operation. The keys are used to set up and calibrate the 2020ComboPRO. All information entered with the keys and stored in the 2020ComboPRO’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 2020ComboPRO is turned on.

General Operation

The 2020ComboPRO is a microprocessor-controlled air monitor for measuring the presence of photoionizable compounds in air at parts-per-million levels. The block diagram in Figure 2 shows the main components of the 2020ComboPRO.

Figure 2. The 2020ComboPRO 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 2020ComboPRO is turned off.

A pump continuously pulls the air under test through the 2020ComboPRO’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 2020ComboPRO’s display and, depending on the values entered through the 2020ComboPRO’s keypad, an alarm status may be displayed and an audio signal may be heard.

The 2020ComboPRO 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.

34 ISP-074-575-P1D

Page 42

In TVOC mode, the 2020ComboPRO does not distinguish one type of compound from another, but displays a number indicating the total concentration of all photoionizable compounds in the sample.

In TVOC mode, a standard of isobutylene at a known concentration may be used for setting the sensitivity. If the 2020ComboPRO is calibrated with isobutylene, it displays concentrations in units equivalent to ppm of isobutylene.

In TVOC mode, the 2020ComboPRO 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 2020ComboPRO. However, all response factors in TVOC mode are based on an isobutylene calibration.

For benzene measurements in GAS mode, a pre-filter tube holder and benzene prefilter tube are installed, and calibration with a known concentration of benzene is advised.

Photoionization Detector

The 2020ComboPRO’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.

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 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.

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 100 ppm isobutylene (Part No. MX350012). 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).

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

Accessory Gas Bag on page 67 for instructions.

Field Operation

For field operation, the 2020ComboPRO Field Kit (Part No. MX750080) is available. The field kit includes a carrying case, a computer cable kit, a calibration regulator, a spare battery pack, and a ProComm software CD.

Refer to the check list in on page 71 to ensure you have all the necessary accessories and equipment before beginning field operation.

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 2020ComboPRO.

6. Attach the connector from the charged battery pack to the 2020ComboPRO.

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

7. Place the battery pack in the 2020ComboPRO 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 overtighten the screws as you will damage the case.

Charging the Battery Pack

NOTE: Only use the AC adapter specified for use with the 2020ComboPRO. Using another

AC adapter will result in damage to the battery pack, the 2020ComboPRO or the adapter itself.

ISP-074-575-P1D 39

Page 47

To charge the battery pack:

1. Plug the AC adapter into the jack located on the bottom of the 2020ComboPRO.

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 above the front display on the 2020ComboPRO 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 2020ComboPRO.

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 2020ComboPRO.

40 ISP-074-575-P1D

Page 48

If you are charging the battery pack in the instrument you can use all the features of the 2020ComboPRO while the battery pack is being charged.

Leaving the AC adapter connected to the 2020ComboPRO will not harm the battery or the AC adapter in any way. If the 2020ComboPRO 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.

Display

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

Graphic Display

The 2020ComboPRO uses an 8 line graphic display. The display will always be used for reporting detected concentration. In order to accommodate the range of concentrations the 2020ComboPRO can detect, the meter reading will be reported using one of two resolutions. A resolution of 0.1 ppm will be used for concentrations below 100 ppm, and a resolution of 1 ppm will be used for concentrations between 100 ppm and 10,000 ppm.

Figure 5. The 2020ComboPRO 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 2020ComboPRO is designed for ease of use with a logically organized internal menu structure/user interface.

Figure 14. Interval Mode Display

GAS Mode

In GAS mode, the benzene pre-filter tube (Part No. F1760161) is used to measure benzene. The GAS mode is a filter tube mode, so all benzene measurements require the installation of the pre-filter tube holder (Part No. A1790500) and one of the benzene pre-filter tubes. The benzene pre-filter tube, which is mounted at the head of the tube holder, adsorbs all substances with the exception of benzene in order to selectively measure benzene. The entire process is menu driven. The benzene measurement value is displayed after 45 seconds.

Activating the GAS mode opens a dialog which calls for a device calibration. The benzene measurement screen is displayed after installation of the benzene pre-filter tube.

Figure 15. Gas Mode Display for Benzene Measurements

The following values are displayed: benzene concentration in ppm, STEL value, the highest benzene measurement value recorded so far (SMAX), the amount of

ISP-074-575-P1D 47

Page 55

measurements already carried out (SAMP) – corresponds with the amount of benzene pre-filter tubes already used, and the sampling interval period of 45 seconds (SECS). Pressing the VIEW key shows the datalogger measurement values. Pressing the MENU key takes you back to the selection menu. Pressing the SAMPLE key starts the measurement: the pump is activated and measured air is drawn through the benzene pre-filter tube for 45 seconds. The measurement status is indicated by the flashing word SAMPLING. The display starts at 45 seconds under SECS and counts down to 0. So, the displayed number shows the remaining measuring time. SAMPLE DONE signaled in the display indicates that the measurement is finished.

The benzene pre-filter tube is a one-use device and should not be used for any additional measurements. Pressing the SAMPLE key will call up the information that the benzene pre-filter tube in use is no good and that a new benzene pre-filter tube must be put into the pre-filter tube holder. Only after inserting a new tube will pressing the SAMPLE key start a new measurement.

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, the right soft button is used 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.

A cancel option is not available to the user as a value must be entered.

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 2020ComboPRO also has an audio alarm and an alarm LED. Different alarms are identified by the frequency at which the 2020ComboPRO 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.

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 2020ComboPRO 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.

ISP-074-575-P1D 49

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

User Interface – Basic Menu

The 2020ComboPRO is designed for ease of use with a logically organized internal menu structure/user interface. The 2020ComboPRO User Menus as shown in Figures 6-11.

The 2020ComboPRO has three soft keys under the graphic LCD display which always show the available functions of the soft keys in any screen.

Operation Modes TVOC Monitoring Modes

In TVOC mode, Total Volatile Organic Compounds are detected.

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 2020ComboPRO display. Logging Off

will continuously display the concentration of total volatile compounds present that the 2020ComboPRO can ionize. The reading is updated approximately once per second. In Logging Off mode, the only soft key displayed is MENU.

MENU selects the 2020ComboPRO’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 2020ComboPRO 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. In Tag mode, the soft keys are VIEW, TAG and MENU.

VIEW selects datalogger review.

TAG selects “No Label”, “Background”, or “Sample”.

MENU selects the 2020ComboPRO’s internal menu for the 2020ComboPRO 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 2020ComboPRO display. Interval automatically calculates and updates STEL, TWA, and PEAK readings. Interval mode also automatically stores

50 ISP-074-575-P1D

Page 58

these readings in the 2020ComboPRO’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 the2020ComboPRO’s internal menu for the 2020ComboPRO 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 2020ComboPRO 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 2020ComboPRO. 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 2020ComboPRO. You can display the results of the calculations by selecting Interval mode.

PEAK Mode

The PEAK mode displays the current detected concentration. The reading is updated once a second. In the background, the 2020ComboPRO 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”

GAS Monitoring Mode for Benzene Measurement

In GAS mode, the benzene pre-filter tube (Part No. F1760161) should be used to measure benzene. The GAS mode is a filter tube mode, so all benzene measurements require the installation of the pre-filter tube holder (Part No. A1790500) and one of the benzene pre-filter tubes. The benzene pre-filter tube, which is mounted at the head of the tube holder, adsorbs all substances with the exception of benzene in order to selectively measure benzene. The entire process is menu driven. The selective benzene measurement value is displayed after 45 seconds.

Figure 16. 2020ComboPRO with pre-filter tube holder

Initial Display

When the 2020gasPRO powers up the user is asked whether or not the instrument

should be calibrated. If “yes” is selected, the instrument enters calibration mode and the user should follow the display prompts. If “no” is selected, the instrument

display goes directly to Sample mode.

The following values are displayed: benzene concentration in ppm, STEL value, the highest benzene measurement value recorded so far (SMAX), the amount of measurements already carried out (SAMP) corresponds with the amount of benzene pre-filter tubes already used, and the sampling interval period of 45 seconds (SECS). Pressing the VIEW key shows the datalogger measurement values. Pressing the MENU key takes you back to the selection menu. Pressing the SAMPLE key starts the measurement: the pump is activated and measured air is drawn through the benzene pre-filter tube for 45 seconds. The measurement status is indicated by the flashing word SAMPLING. The display starts at 45 seconds under SECS and counts

52 ISP-074-575-P1D

Page 60

down to 0. So, the displayed number shows the remaining measuring time. SAMPLE DONE signaled in the display indicates that the measurement is finished.

The benzene pre-filter tube (Part Number F1760160) is a one-use device and cannot be used for a second measurement. Repeatedly pressing the SAMPLE key will call up the information that the benzene pre-filter tube in use is no good and that a new benzene pre-filter tube must be put into the pre-filter tube holder. Only after inserting a new tube will pressing the SAMPLE key start a new measurement.

Benzene Sample Analysis Mode

The user is prompted through the basic procedures for taking benzene samples.

At the end of the sample period, the user is advised that the tube life is used up and a new tube should be inserted.

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.

The recorded data can now be reviewed and edited. Recorded data can also be printed using the PC. For each averaging interval, the 2020ComboPRO 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 2020ComboPRO 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.

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 2020ComboPRO stops accumulating data and the TWA is complete.

Interval mode logs readings at user-selected intervals of 1 second to 999 seconds.

Figure 17. Interval time adjustment

Interval simultaneously displays the STEL, TWA, and PEAK reading along with the instantaneous reading. The 2020ComboPRO’s datalogger can store up to 200 hours of 1 minute sample entries. The interval you select will determine the period of operation. At the end of the period, the datalogger will be full and you will see the “Data Log Full” status.

Response Factor Library

The response of a compound to a PID 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 2020ComboPRO using an isobutylene calibration to mimic the 2020ComboPRO response as if the 2020ComboPRO was calibrated using that specific single compound.

General Information

In situations where only a single pure compound is present in air, the 2020ComboPRO should be calibrated with a standard of that specific compound as span gas. The 2020ComboPRO’s 15 memory slots can be used to store calibration information for 15 different span gases.

NOTE: Even if the 2020ComboPRO 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 2020ComboPRO 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 2020ComboPRO’s reading, then displays and records it.

The list of response factors is available directly from INFICON’s web site at:

www.INFICON.com. This list should be used only for concentrations up to 500

ppm of the specific compound, as response factors can change with concentration.

60 ISP-074-575-P1D

Page 68

CAUTION

The 2020ComboPRO is a total VOC instrument and will ALWAYS respond to all ionizable compounds present in a sample. It is the responsibility of the user to be aware of the limitations of PID instruments.

62 ISP-074-575-P1D

Figure 21. Sample Analysis Mode

Page 70

The initial prompt asks if the user wishes to calibrate the 2020ComboPRO. The user can choose to calibrate the unit or simply start the monitoring activity. The display will next alert the user that tube life is used up, and to then continue. The user is then directed to insert a pre-filter tube and to then continue.

For analysis of benzene concentrations, press the sample key. An air sample is drawn into the benzene pre-filter tube and 2020ComboPRO for 45 seconds. At the conclusion of the sample, the benzene concentration will be presented on the display, in addition to STEL and SMAX readings.

Calibration Technical Description

Periodic calibration is required to compensate for the 2020ComboPRO output changes due to inlet filter restriction, ionization chamber contamination, lamp cleanliness, pump wear and other factors.

During calibration, the 2020ComboPRO is first exposed to zero air. A small (zero) signal is generated. This zero signal is stored by the microprocessor.

The 2020ComboPRO 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 2020ComboPRO readings are always relative to the calibration gas. After calibration with isobutylene, the 2020ComboPRO will respond directly in units equivalent to isobutylene. Most volatile organic compounds will be detected by the 2020ComboPRO. 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 2020ComboPRO readings give an indication of the total ionizables present and their concentration relative to the calibration gas.

Calibration Introduction

The 2020ComboPRO must be calibrated in order to accurately display sample concentrations. First, a supply of zero air, which contains no ionizable gases or vapors, is used to set the 2020ComboPRO’s zero point. Then, a calibration gas, containing a known concentration of a photoionizable gas or vapor, is used to set the sensitivity.

Clean indoor ambient air may be substituted for a cylinder of zero air. Due to the 2020ComboPRO’s sensitivity, outdoor air is usually unsuitable for calibration unless the activated charcoal filter (F1760176) and filter tube holder (A1790500) is used.

Commercially sourced zero air should not have more than 0.1 ppm total hydrocarbons (THC).

ISP-074-575-P1D 63

Page 71

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 Accessory Gas Bag on page 67 for instructions.

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.

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 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 off the regulator outlet. Open the gas cylinder valve slowly and check for leaks. Adjust the delivery pressure and then open the regulator outlet valve.

11.7 eV UV Lamp General Information

The 2020ComboPRO is equipped with a standard 10.6 eV UV lamp. An 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 84. When you install a UV lamp other than the standard 10.6 eV 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

The 11.7 eV 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. Disruption of the lattice causes the crystal to turn a yellowish color, and performance declines.

NOTE: Due to the lamp window limitations, the useful life of the 11.7 lamp is limited, and it should be used sparingly.

Unlike other 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 2020ComboPRO:

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

84.

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

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

78 ISP-074-575-P1D

Page 86

3. Calibrate the 2020ComboPRO. See Calibration Using the Flow-Match Regulator on page 65.

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

5. Recalibrate the instrument every 15 minutes of operation.

6. After 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 Cleaning the Lithium Fluoride Window on page 87.

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.
