PID Theory and Definitions
2 PID Theory and Definitions
To support the safe and effective operation of the ALTAIR 5X PID, MSA believes operators should have
a working knowledge of how the device functions, not just how to make it work. The information
presented in this section supplements the hands-on operational instruction provided in the rest of the
manual for the PID.
PID Theory
A photoionization detector (PID) uses an ultraviolet lamp to ionize the compound of interest. A current
is produced in proportion to the concentration of the VOC present, and the concentration of the
compound is shown on the device display.

3 UV lamp 7 DC Source
4 Electrodes 8 Microprocessor
Zero Gas
Zero gas is a reference gas used during calibration to zero the device. When a zero gas with no hydrocarbon content is introduced to the device, the detector will still respond with a small signal. This signal
is a result of secondary background processes. During calibration, zero gas is applied to quantify the
ALTAIR® 5X PID
US
11
PID Theory and Definitions
background ionization current.When only measuring concentration changes relative to a reference
ambient environment, fresh air can be used as the zero gas. When background hydrocarbon vapors
are present, MSA recommends using zero gas air.
Span Gas
Span gas is a reference gas used during calibration to determine the slope (response per unit concentration) of the calibrated response curve.
For the 0-2000 ppm PID sensor the only allowable calibration gas is 100 ppm isobutylene.
See Chapter 4.10 "Calibration" for calibration instructions.
Response Factors
When a compound is ionized by photoionization, the ionized molecules are collected and converted to
a current. This response is a characteristic property of the specific compound which is influenced by
its molecular structure. The slope of the response curve (defined in picoamperes per ppm) is different
for different chemicals. To properly report the concentration for a given sample gas, the ALTAIR 5X PID
uses response factors. See Chapter 10 "PID Response Factor Table", for instructions on using the preprogrammed list of response factors.
WARNING!
It is very important to have an understanding of PID basics when changing PID settings. Failure to
properly identify the VOC gas being measured and/or failures to select the correct Response Factor
alarm values (exposure, STEL, TWA) that match the desired Response Factor and/or the correct lamp
will result in erroneous readings or erroneous alarm limits that could cause death or serious personal
injury.
The response factor is defined as the ratio of the detector response for isobutylene to the detector
response for the sample gas. Response factors for a wide range of substances have been determined
experimentally. These response factors are programmed into the device. Note that the calibrated
response curve, and all programmed response factors are relative to isobutylene. Isobutylene has a
response factor of one.
The response factor is a multiplier that compensates for the difference between the response of the
sample gas and the response of isobutylene at 100ppm. Whenever the device detects the presence
of a VOC, it uses the response factor for the user-assigned target gas to convert the signal to the
correct, concentration. This is done by multiplying the equivalent isobutylene response by the response
factor for the set sample gas. The isobutylene response curve is calculated at every calibration.
If the response factor is known, a device calibrated with isobutylene can be used to calculate the actual
concentration of a target gas.
Calculating a Response Factor
To determine a response factor for a target chemical, perform the following simple procedure:
(1) Calibrate the ALTAIR 5X PID using isobutylene as the span gas.
(2) On the device, set the sample gas name to isobutylene.
(3) Apply a known concentration of the target chemical to the device and note the concentration
reported in the display.

PID Theory and Definitions
For example:
An operator is using a device that has been calibrated on isobutylene. The sample gas is set to isobutylene. While using this device to sample for hexane, the display reads 100 ppm. Since the response
factor for hexane is 4.5, the actual concentration of hexane is:
Actual hexane concentration = 4.5 x 100 ppm = 450 ppm.
For example:
A device is calibrated on isobutylene, and has isobutylene defined as the sample gas. When sampling
106 ppm of benzene in air, the device reports a concentration of 200 ppm. In this example, the
response factor for benzene relative to isobutylene would be:
RF benzene =
When surveying, if benzene is selected as the sample gas in the Response Factor page, 0.53 will be
used by the device as a response factor. The device will use this response factor to automatically
correct the displayed concentration into PPM benzene.A target gas with a response factor between
zero and one implies that the device has a higher detector response for that gas when compared to
isobutylene. If the response factor is greater than one, the device has a lower detector response for
this gas when compared to isobutylene.
WARNING!
It is very important to select the correct lamp setting during PID setup since PID response factors for
a target chemical relative to isobutylene are different depending on what energy PID lamp is installed.
See Chapter 4.5 "Device Setup" for setup instructions. Failure to follow this warning can result in inaccurate readings that could lead to serious injury or death.

The device vibrates when any alarm condition is active. This can be turned OFF
through the SETUP- ALARM OPTIONS menu ( chapter 4.5 "Device Setup").
The device is equipped with an audible alarm.
The horn can be turned OFF through the SETUP- ALARM OPTIONS menu
( chapter 4.5 "Device Setup").
The InstantAlert exclusive feature allows the user to manually activate an audible
alarm to alert those nearby to potentially dangerous situations. Holding the
button for approximately 5 seconds while in Normal Measure Mode activates
the InstantAlert alarm. Access to this feature may be restricted by user settings.
See chapter 4.5 "Device Setup" for means to allow/disallow user access.
If MotionAlert is turned ON ( chapter 4.5 "Device Setup"), the device activates a
"Man Down" alarm if motion is not detected within 30 seconds. The Alarm LEDs
flash, and the horn activates with an increasing audible frequency. MotionAlert is
always turned OFF when the device is turned OFF.
Access to this feature may be restricted by user settings. See chapter 4.5 "Device
Setup" for means to allow/disallow user access.
Stealth Mode disables the visual, audible and vibrating alarms. MSA recommends
that this feature be left in its default "OFF" state. Stealth mode can be turned ON
through the SETUP - INSTRUMENT OPTIONS menu ( chapter 4.5 "Device
Setup"). On the display, all three alarm icons are shown as OFF.
The device evaluates the condition of the sensors during Calibration.
As the end of a sensor’s life approaches, a warning is provided. While the sensor
is still fully functional, the warning gives the user time to plan for a replacement
sensor to minimize downtime. The Sensor Life indicator displays during ongoing
operations as a reminder of a sensor’s pending end of life.
When a sensor’s end-of-life is reached, sensor calibration will not be successful,
and the user is then alerted by a Sensor Life Alarm. A flashing Sensor Life
indicator displays during ongoing operations until the sensor is replaced and/or
successfully calibrated.
On the display, each displayed gas will have its own Sensor Life indicator. If a
sensor is in end-of-life warning, its indicator will be an orange . If a sensor has
reached end-of-life, it is in alarm and its Sensor Life indicator will be a continuous
blinking red .
See chapter 4.10 "Calibration" for additional details on Sensor Life determination
and indication.
The backlight automatically activates when any front panel button is pressed and
remains ON for the duration of user-selected timeout.

Description
Fig. 6 Alarm Conditions (here High Alarm)
The carbon monoxide channel in the device is equipped with an internal filter. The purpose of this filter
is to protect the CO sensor from acid gases (H2S, SO2, etc.) and from the hydrocarbons that the device
is intended to measure, including the calibration gas, isobutylene. In normal use, an interferent signal
for calibration or bump checking the device should not be observed on the CO channel. However,
exposure to large amounts of certain hydrocarbons (either long exposure times or high concentrations)
can overwhelm the filter and appear as signals on the CO channel.
In normal operation, after the hydrocarbon exposure is ended, the filter is designed to outgas absorbed
hydrocarbons at a rate that will not cause a signal on the CO channel. However, if the unit is exposed
to high temperature (>40°C), this desorption rate increases and spurious signals may be observed on
the CO channel due to gassing of previously absorbed hydrocarbons. Typically the CO sensor will
recover within 24 hours but extremely high exposures can extend this time. After the recovery period
if the CO sensor can no longer be calibrated or shows an elevated reading that cannot be brought to
zero with a zero calibration, the CO sensor should be replaced.
WARNING!
Extremely high levels of VOCs will send the CO sensor into alarm and the sensor may not
recover or the recovery period will be significant.
Take the impact on sensor performance into account when installing sensors.
If the gas concentration reaches or exceeds the alarm set point or the STEL or TWA limits, the:
• alarm message displays and flashes in combination with the corresponding gas concentration
• backlight turns on
• alarm sounds (if active)
• alarm LEDs flash (if active)
• vibrating alarm triggers (if active)
3.8 Monitoring Oxygen Concentration
The device monitors the oxygen concentration in ambient air. The alarm set points can be set to activate on two different conditions:
• Enriched - oxygen concentration > 20.8% or
• Deficient - oxygen concentration < 19.5%.
While the device can detect up to 30% oxygen in the ambient air, it is approved for use only up to 21%
oxygen-content.

• vibrating alarm triggers (if active)
The LOW alarm (oxygen deficient) is latching and will not automatically reset when the O
tion rises above the LOW set point. To reset the alarm press the button. If the alarm is latching, the
button silences the alarm for five seconds. Alarms can be made latching or unlatching via MSA Link
software.
False oxygen alarms can occur due to changes in barometric pressure (altitude), humidity or extreme
changes in ambient temperature.
It is recommended that an oxygen calibration be performed at the temperature and pressure of use.
Be sure that the device is in known fresh air before performing a calibration.
3.9 Monitoring Combustible Gases

• backlight turns on
• alarm sounds (if active)
• alarm LEDs flash (if active)
• vibrating alarm triggers (if active)
To reset the alarm press the button.
False VOC alarms can occur due to changes in barometric pressure (altitude), humidity or
extremechanges in ambient temperature.
It is recommended that a VOC calibration be performed at the temperature, humidity and pressure of
use.
Be sure that the device is in known fresh air before performing a calibration. For optimal lamp strike,
the PID lamp should be started within the normal temperature range.
Description
US
When the device is calibrated in an dry, air conditioned environment and taken to a high
temperature and high humidity outdoor environment, a VOC Low or High alarm may be
triggered by this sudden change. It is recommended that the PID sensors be cleaned
prior to this transition to avoid this situation, or to acclimate the sensor to the outdoor
conditions in a known safe area.

3.11 Displaying Current Response Factor
The current Response Factor (RF) is displayed at device startup along with the PID lamp potential in
eV value, sensor range and VOC gas type.
During operations, the RF can be displayed through several menus. If the Menu Enable option is On,
use the button on the Main Measuring page to scroll through the menu options and select YES on
"Change VOC Gas?". Selecting any gas on this page will display the 8 character gas name, the
Response Factor, the Maximum Value of the VOC gas and the current High and Low Alarm values.
Description
The Maximum Value is calculated by multiplying the sensor range by the RF. For example, the
Max Value for Hexane is 2000 *4.5 = 9000 ppm. The maximum value cannot exceed 9999 ppm .
It is the responsibility of the user to change the VOC Low and High Alarms as appropriate
for the applied RF. The selection of the alarm limits must be under the direction of a qualified safety professional who has carefully evaluated the specific hazards of the jobsite
where it will be used and who is completely familiar with the product and its limitations.
A complete list of the 8 character gas name and Response Factors for all VOC gases is contained in
chapter 10 "PID Response Factor Table".
