Cavity Ring-Down Spectroscopy Analyzer for Carbon Methane and Water - the Global Gold Standard

CRDS Analyzer for CO₂/CH₄/H₂O in air - G2301

Chosen by the World Meteorological Organization as the Global Gold Standard - Simply the Best Analyzer for Greenhouse Gas Analysis

• Global #1 in precision and accuracy, and portability
• The lowest guaranteed drift of any instrument
• Unique water correction feature automatically calculates and reports dry mol fraction
• Advanced electronics lowers noise, improves data quality
• Innovative software adds user programming and interface flexibility 

Only Picarro's G2301 offers simultaneous, precise measurement of CO₂, CH₄ and H₂O as well as PPB sensitivity - in any environment. This completely revamped analyzer has best-in-class precision and accuracy with far less drift over time than any other analyzer on the market. While all other analyzer products require complex and time-consuming gas drying technologies for accurate measurements, the G2301 eliminates this need and allows for high-precision measurements of ambient air with no pre-processing required. These qualities and more have made Picarro analyzers the global gold standard for high-precision measurements of the three most important greenhouse gases. 

The need for accurate measurement of the three principal greenhouse gases is growing rapidly. These requirements are being driven by the need to understand global warming, conduct climate modeling, and to comply with protocols, international agreements, and national and local verification. The Picarro G2301 is the only instrument that can make all these measurements and also act as a direct reference/standards transfer. Specifically, its compact portability means the G2301 operates equally well in the reference laboratory, as a portable spot measurement tool, or remotely as an unattended continuous monitoring station. It combines parts per billion sensitivity with the dynamic range necessary to measure undiluted ambient atmospheric levels of these species. And because it is a fully self-contained, rugged instrument with no moving parts, the G2301 can operate for up to months in the field without the use of calibration gases.

Because the G2301 analyzer is based on CRDS technology there is no crosstalk between the CO₂, CH₄ and H₂O detection channels and all three channels are unaffected by changes in other gas species. Also, Picarro builds in sophisticated pressure and temperature controls that are required for accurate spectroscopy. No other analyzer company has these types of pressure and temperature controls. As a result, data collected with Picarro products are immune to changes in ambient temperature and pressure even in cases of relatively drastic shifts.
