G2203 Gas Concentration Analyzer

Measures CH4 and C2H2

The Picarro G2203 gas concentration analyzer provides simultaneous, precise measurement of methane (CH4) and acetylene (C2H2) at parts-per-billion (ppb) sensitivity with negligible drift for measuring fugitive emissions of CH4 from landfills, or other extended CH4 sources, using a C2H2 tracer measurement for quantifiable emission rates. 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 C2H2 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 2 seconds is 3 ppb for CH4 and <0.6 ppb for C2H2. Maximum drift at standard temperature and pressure (STP) over 8 hours is <4 ppb for CH4 and 1.5 ppb for C2H2. 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.
