Gas Analyser Kit

The Clean Air Task Force (CATF) utilizes a specialized gas analyser kit, specifically the ABB GLA-131 model, to detect methane and carbon dioxide emissions. The tool uses laser absorption spectroscopy to identify gas concentrations with high precision, including methane detection at levels below 1ppb. While the analyser can detect diffused emissions kilometers away from a source and confirm the gas identity, it is used for qualitative detection of concentrations rather than the quantification of emission rates, which would require additional meteorological data and scientific expertise. CATF employs the analyser as a complement to optical gas imaging (OGI) cameras to provide a more comprehensive view of emissions from sources such as landfills, gas capture wells, and anaerobic digesters.

• The CATF gas analyser kit uses the ABB GLA-131 model to measure concentrations of methane, carbon dioxide, and water vapor, with a methane detection precision of less than 1ppb.
• The device operates via laser absorption spectroscopy, which identifies gases by their specific light absorption patterns, allowing for the detection of emissions even when the operator is far from the source or positioned downwind.
• The gas analyser complements optical gas imaging (OGI) cameras by detecting diffused emissions over distances of several kilometers and providing unambiguous confirmation that the gas is methane, whereas OGI cameras require a direct line of sight and are better for high concentrations near the source.
• CATF uses the kit for qualitative detection of gas concentrations rather than quantifying emission rates, as the latter requires sophisticated calculations and precise local meteorological measurements.
