G2301 gas concentration analyzer measures CO2, CH4, and H2O

The Picarro G2301 gas concentration analyzer can accurately measure carbon dioxide (CO2), methane (CH4) with a sensitivity of parts per billion (ppb), and water vapor (H2O) with a sensitivity of parts per million (ppm) simultaneously. The drift generated for atmospheric science, air quality, and quantitative emission applications can be ignored. This analyzer meets the performance requirements of the World Meteorological Organization (WMO) and the Integrated Carbon Observing System (ICOS) for atmospheric monitoring of CO2 and CH4.

• Simultaneous and continuous measurement of three atmospheric trace gases

• Billion parts per billion (ppb) sensitivity, accuracy, and precision, with extremely low drift

• Complies with the international environmental and atmospheric monitoring requirements of WMO and ICOS

• Equipped with water vapor correction function, automatically reporting dry gas mole fraction

For CO2, the accuracies at 5 seconds and 5 minutes are<70 ppb='' and=''>70><25 ppb, respectively. For CH4, the accuracies are=''>25><0.5 ppb='' and=''>0.5><0.22 ppb, respectively. For='' CO2 and='' CH4, the maximum drift within 24 hours at standard temperature and pressure='' (STP)='' is='>0.22><120 ppb=' 'and='>120><1>, respectively

**The typical performance is defined as the median of the test results of 36 G2301 analyzers manufactured in sequence. Results can be requested.

*Picarro calculates drift by subtracting the minimum value from the maximum value of the 50 minute average data obtained from a 30 hour experiment.
