5.0 Calibration
5.1 Gas Module Calibration
All the Gas modules in the IQM can be calibrated in the unit by applying certified gas to the IQM inlet. All
Zero and span calibrations or checks should be performed with humidified air and use single gas mixtures
in a balance of air. If the IQM is to be deployed in environments with very low or high absolute humidity it is
recommended that the sensors be zero and span calibrated under those conditions, since the sensors are
slightly sensitive to changes in absolute humidity.
Zero and span adjustments on the IQM60 V5 are performed by adjusting the OFFSET and GAIN values
under the Calibration menu. The equation that relates the OFFSET and GAIN to the Gas reading is given
below:
Gas Reading = GAIN x (Module Reading - OFFSET)
All the Gas modules in the IQM can be calibrated in the unit by applying certified gas to the IQM inlet.
All zero and span calibrations or checks should be performed with gas mixtures in a balance of
air. Note: the calibration standard may be in a balance of N2 but it should be diluted with air
prior to presenting to the IQM.
Fluorocarbon (PTFE, FEP or PFA) tubing and fittings should be used for all sample lines.
Warm up the IQM for at least 12 hours before attempting a gas sensor calibration
5.1.1 Nafion Humidifier
ANafion tubing membrane humidifier is supplied with the IQM which can be used to humidify the air
delivered to the IQM during calibrations. Two lengths of 1/4” Teflon tubes are supplied to enable
connection to sample lines and the IQM inlet.
Span gas and zero air is typically dry (~0%RH) and the sensors used in the IQM require 50 +/-20% RH for
best performance. The Nafion membrane is selectively permeable to water vapor (although some other
compounds such as ammonia, alcohols, acetone, and acetic acid may also be transported across the
membrane see www.permapure.com for further information) and the direction of transport is driven by the
concentration gradient across the tubing wall. The humidifier is designed to extract water vapor from the
surrounding ambient air and transfer this into the dry span or zero gas source. The resultant humidity in the
sample gas is roughly half of that of the ambient air. If the surrounding air humidity is less than 50% it is
recommended that the membrane is positioned above a water bath to increase the humidity in the sample
air. Also, Make sure that the air surrounding the membrane is not contaminated with hydrocarbons that
could be transported across the nafion to the sensors. If in doubt contact Aeroqual.

5.1.2 Zero verification using Gas Treatment Module
The Gas Treatment Module contains a zero air scrubber which can be automatically or manually turned on
to periodically measure the zero of the instrument. The automatic zero verification is set in the
Configuration file under Zero Readings. This turns on the gas treatment module for 30 minutes during
which time the sensors continue to measure. This procedure is repeated at a user defined interval between
1and 255 hours. It is recommended that this procedure is used when making field measurements.
5.1.3 Zero calibration
5.1.3.1 Using Gas Treatment Module
You may use the zero air scrubber in the Gas Treatment Module to undertake a manual zero calibration.
Before doing this you should check that the media are in good condition or if possible replace with fresh
media.
1. Turn on the zero scrubber manually by clicking on PC software, Tools- >Turn On Zero Scrubber.
2. Allow the AQM to sample until stable readings are obtained (about 30 - 60 minutes).
3. Adjust the OFFSET values for each gas sensor via the Calibration --> Calibrate OFFSET-->enter
password “password”--> select gas--->enter new OFFSET
new OFFSET = old OFFSET + AQM60 gas reading
5.1.3.2 Laboratory Zero calibration
The IQM can be re-zeroed via the PC software using a zero air source with relative humidity of 50% +/-
20%. Aeroqual can supply a humidifier that uses a Nafion membrane to humidify the air.
1. Connect a source of zero air to the IQM through the sample port using ¼ inch Teflon tubing. Use a
Tfitting to ensure the IQM is sampling the gas flow at atmospheric pressure. The zero air should
be at least 1.5 LPM (check there is excess flow at the exhaust of the T fitting).
2. Allow the IQM to sample until stable readings are obtained (about 30-60 minutes).
3. Adjust the OFFSET values for each gas sensor via the Calibration --> Calibrate OFFSET-->enter
password “password”--> select gas--->enter new OFFSET
new OFFSET = old OFFSET + AQM60 gas reading
5.1.4 Span calibration
The sensors can be manually span calibrated by modifying the individual gain factors for each sensor.
Introduce a known concentration of span gas into the instrument and adjust the gain factor to set the
correct concentration reading. Note: a sensor zero point calibration should always be performed before
undertaking a span calibration.
5.1.4.1 Span gas
Span gas mixtures should be single gas mixtures that are certified and be in a balance of air.
DO NOT USE MIXTURES THAT CONTAIN MORE THAN ONE SPAN GAS COMPONENT
DO NOT USE A SPAN GAS IN A BALANCE OF NITROGEN UNLESS DILUTION IS GREATER
THAN 50 TIMES WITH ZERO AIR.
The mixture should also be humidified to about 50 +/-20% RH by either using a Nafion membrane
humidifier or by bubbling the zero grade air through water prior to mixing with the gas standard. Aeroqual
can supply a Nafion humidifier which is suitable for IQM units containing O3, NO2, CO, SO2 and VOC
sensor modules. Excessive gas concentrations should be avoided as these may damage the sensors or
cause contamination of the internal tubing. Recommended span points for gas sensors are given in the
table below.

calibrators, or ozone calibrators.
5.1.4.2 Span calibration procedure
1. Perform zero calibration.
2. Connect a source of span calibration gas to the IQM through the sample port. Use a T fitting to
ensure the IQM is sampling the gas flow at atmospheric pressure. The span gas flow should be at
least 1.5 LPM (check there is excess flow at the exhaust of the T fitting).
3. Allow the IQM to sample the gas until a stable reading is obtained (about 30 minutes).
4. Adjust the IQM60 sensor gain factor to set the correct concentration reading

5.2 Particle Counter Calibration
Flow rate
The sampling flow rate should be checked monthly and adjusted if required. To test the flow rate:
1. Remove the isokinetic probe and connect a flow meter to the barb fitting of the particle inlet using a short
piece of flexible 1/8 “ ID tubing, Tygon tubing is a good choice.
2. Turn on the IQM and note the flow meter reading. The flow rate should be 1.0 +/- 0.05 LPM
3. The flow rate can be adjusted by a screw flow adjuster located underneath the bottom panel of the IQM
(see below). To remove the bottom panel, remove the two screws located at the bottom rear corners of the
casing and the bottom panel lifts off. Use a screw diver to adjust the screw in the T piece fitting. Turn the
screw clockwise to decrease the flow and counter-clockwise to increase the flow.
Zero Check
It is recommended to periodically perform a zero count test as described below. False counts caused by air
leaks or spurious noise will cause errors that are especially apparent when sampling relatively clean
aerosols.
1. Attach a filter with a rating of 0.45µm or better to the particle inlet nozzle. The filter must be large enough
that it does not create a restriction and load down the small vacuum pump inside the IQM. One zero
particulate filter is supplied with the IQM.
2. Since the air passing through the IQM is now virtually particle free the output particle count should be
zero. If it is not, check for leaks around the tubing to the particle counter.
Span Calibration
There are no user serviceable components inside the particle counter instrument. The cover on the particle
counter should not be removed or opened for servicing, calibration or any other purpose except by a factory
authorized person. To do so will void warranty and may result in exposure to invisible laser radiation that
can cause blindness. Contact Aeroqual for service information. Calibrating particle sensors like the one in
the IQM requires specialized equipment and a skilled technician. The particle counter should be factory
calibrated on a yearly basis.
