G2204 Gas Concentration Analyzer

Measures CH4 and H2S

The Picarro G2204 gas concentration analyzer provides simultaneous, precise measurement of methane (CH4) and hydrogen sulfide (H2S) at parts-per-billion (ppb) sensitivity with negligible drift for emissions measurements from landfills, refineries, paper mills, or industrial plants. It can be installed in minutes for stationary monitoring, or it can be coupled using U.S. Environmental Protection Agency geospatial methods for beyond the fence line remote emissions quantification (EPA Other Test Methods 33).

  • Simultaneous and continuous measurement of CH4 and H2S concentrations
  • Parts-per-billion sensitivity, precision, and accuracy with exceptionally low drift
  • Use for stationary monitoring or beyond the fence line remote emissions quantification
  • Rugged and insensitive to changes in ambient temperature

Precision at 5 minutes is 2 ppb for CH4 and 3 ppb for H2S. Maximum drift at standard temperature and pressure (STP) over 8 hours is <4 ppb for CH4 and <20 ppb for H2S. Users can connect remotely and control the analyzer through a standard remote desktop connection or with similar remote login software, and the analyzer can be configured to automatically send out measurement data at regular intervals.
