Safety information for Analyzer utilisation
IR-GAS-600P Analyser is not designed for use in hazardous area. Never use the analyzer in an
EX environment with potential gas explosion risks. Human safety could be seriously
endangered by flame, fire and/or deflagration.
IR-GAS-600P Analyser must be installed on a flat surface (if used as bench-type analyser) or
integrated in a gas analysis cabinet. Avoid locations where the analyzer can be exposed to
vibrations, chocks or intense electromagnetic fields as this can have a negative effect on the
performances of the analyzer.
Do not expose the analyzer to strong artificial light or sun radiations, wind, moisture of rain.
Prevent dust and moisture to enter the analyzer otherwise its good operation will be
impaired.
Gas connections and sample gas conditions
IR-GAS-600P SYNGAS analyser is usually supplied with our optional portable gas washing
unit 。 This unit can also be equipped with an optional powerful gas sampling pump
(requires 220 VAC power supply) to suit all process conditions. In case this accessory is
not supplied with the analyser, the customer shall ensure that the gas conditions at the
inlet of the analyser are in accordance with the following characteristics: free of solid
particles (<1μ), tar and of oil traces, with moisture content between 5 and 95% RH
non-condensing
Before switching ON the analyzer:
- Install the gas analyser on a flat surface
- Connect the gas discharge pipe on the gas out port of the analyser and position the
extremity of the pipe as far as possible from the analyser. Please also take care
about wind direction. Gas venting within an enclosed or non-ventilated area is not
allowed.
Switch ON the analyser
Wait for the complete cycle of preheating has elapsed, or 800 seconds.
Connect the outlet pipe of the gas washing unit to the input port of the analyser
Activate the internal pump of the gas analyser and adjust the flow meter of the gas
analyser at 1L/min. If the analyser is used with the gas washing unit with gas sampling
pump, the pump of the gas analyser does not need to be used.
If the gas is delivered in pressure (> 100 mbar relative) to the analyser, you shall place a
pressure limiting system before the analyser set to 100 mbar to protect it against
excessive pressure peaks (see conditions of the gas below). Excessive pressure may
cause leakage of toxic or explosive gases which can lead to serious accidents.
Sample gas conditions at GAS IN port of the analyser must answer to the following
specifications:
- Moisture: 5 to 95% RH non-condensing.
- Quality: free from solid particles, tar and oil traces
- Temperature: < 50°C

- Pressure in: max. + 100 mbar relative;
Processes with lower gas pressure will require the use of a gas sampling pump.
Processes with higher gas pressure will requires the installation of a pressure reducer
before the analyser to keep the gas pressure constant and limited to max. 100 mbar
relative.
Gas pressure > 500 mbar relative will cause permanent damages to NDIR detectors
- Pressure out: atmospheric pressure
Environmental operation conditions:
- Temperature: +5° to +45°C
- Pressure: atmospheric pressure +/- 10%
- Relative humidity: maximum 0-95%, not condensing.
- Safe area
Notice for electrical connections
Please use the power supply that complies with the power ratings of the analyser, to avoid
fire and/or abnormal operation.
The analyser is intended to be used with its internal batteries offering an operating
autonomy > 6h.
Ensure the power supply is switched OFF before connecting a data transmission line to the
serial RS232 port
Never use the analyser in an EX environment with potential gas explosion risks.
Notice for analyser application
Smoking nearby to the analyser is not allowed and could lead to serious fire
hazards.
Test the response of the gas analyser exclusively on target gases with certified gas
canisters from known concentration. Span gas concentration need to be within 90%
to 100% of the designed full scale range, otherwise the accuracy and linearity of the
analyser can be affected. Use pure nitrogen N2 5.0 quality for zero calibration.
Never let the moisture enter the analyser to avoid electric discharge and risk of
short circuit.
After completion of the measure and before switching OFF the analyser, always
perform a purging cycle of 5 minutes with the pump ON and the analyser located
in fresh ambient air.
Always prevent dust, tar and oil traces for entering the analyser to avoid damages
to the measuring cells.

2 Abstract
IR-GAS-600P is based on NDIR technology to measure the gas concentration of CO, CO2, CH4 and
CnHm(optional), based on TCD to measure he gas concentration of H2, and based on ECD to measure the gas
concentration of O2 at the same time in one analyzer. The BTU calculation is available in IR-GAS-600P.
2.1 NDIR principle
CO, CO2, CH4, C3H8 and other molecules by heterogeneous atoms in the infrared wavelength region with
the absorption spectrum, its absorption intensity follows Lambert - Beer's Law. When corresponding to a
characteristic absorption wavelength of the light waves of gas through the gas is measured, its intensity will be
significantly weakened, the intensity of the gas concentrations in the degree of attenuation related to the
relationship between compliance with Lambert - Beer law. The basic principle of NDIR sensor structure, shown
below,
The basic mathematical model is as follows: most of the organic and inorganic multi-atomic and molecular
gases in the infrared region have a specific absorption wavelength. When the infrared light passes through, these
gas molecules through the specific wavelengths of light intensity by the Lambert - Beer law, said: I = I0e-kpl,
absorption of light intensity i can be expressed as: i=I0-I= I0 (1- e-kpl). Where, I0 is the incident light strong; I is
through the light intensity; l is the thickness of the gas medium, p is the gas density, k is the absorption
coefficient.
