The Picarro G2204 gas concentration analyzer can accurately measure methane (CH4) and hydrogen sulfide (H2S) simultaneously, with a sensitivity of parts per billion (ppb). The drift generated by emission measurements for landfills, refineries, paper mills, or industrial plants can be ignored. This analyzer can be installed in just a few minutes for static monitoring applications, as well as for remote quantitative emission applications that exceed the warning line. It is coupled using the US Environmental Protection Agency's Geospatial Method (EPA's other testing method OTM 33).
Simultaneous and continuous measurement of CH4 and H2S concentrations
Billion parts per billion (ppb) sensitivity, accuracy, and precision, with extremely low drift
Application for static monitoring or remote quantification of emissions beyond warning lines
Durable and sturdy structure, insensitive to environmental temperature changes
The accuracy of CH4 is 2 ppb (1 σ, 5 seconds). The accuracy of H2S is 1 ppb (1 σ, 5 minutes), and the minimum detection limit is 3 ppb (3 σ, 5 minutes). For CH4 and H2S, the maximum drift within 8 hours at standard temperature and pressure (STP) is<4 ppb='' and=''>4><3 ppb='' (peak to peak, 50=''>3>), respectively
