The ABB laser-based gas analyzers build on theheritage and extensive track record of Los GatosResearch analyzers, using patented Off-AxisIntegrated Cavity Output Spectroscopy (OA-ICOS)technology, the latest evolution in tunable diode laserabsorption spectroscopy.ABB’s microportable gas analyzers (GLA131-GGA)reports measurements of methane, carbon dioxideand water vapor simultaneously in a package that iscompact, crushproof and travels anywhere. Smallenough to be hand-carried (even on-board aircraft)and requiring less than 35 watts, the GLA131-GGAoffers opportunities to measure greenhouse gasesanywhere.As with all OA-ICOS analyzers, the GLA131-GGA is fastand simple to use which makes it ideal for fieldstudies, compliance monitoring, air quality studiesand soil flux studies, and wherever sensitivemeasurements of greenhouse gases are needed.
