The Picarro G2301 gas concentration analyzer provides simultaneous, precise measurement of carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb) and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification. It meets the World Meteorological Organization (WMO) and Integrated Carbon Observation System (ICOS) performance requirements for CO2 and CH4 atmospheric monitoring.
Simultaneous and continuous measurement of three atmospheric trace gases
Parts-per-billion sensitivity, precision, and accuracy with exceptionally low drift
Compliant with WMO and ICOS international ambient atmospheric monitoring requirements
Water correction automatically reports dry gas mole fractions
Precision at 5 seconds and 5 minutes is <70 and <25 ppb for CO2 and <0.5 and <0.22 ppb for CH4. Maximum drift at standard temperature and pressure (STP) over 24 hours is <120 ppb for CO2 and <1 ppb for CH4. Water correction software automatically reports dry gas mole fractions to help reduce research complexity and consumable costs.
