The Picarro G5310 gas concentration analyzer provides simultaneous, precise measurement of nitrous oxide (N2O), carbon monoxide (CO) at parts-per-trillion (ppt), 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 N2O and CO atmospheric monitoring.

• Simultaneous and continuous measurement of N2O and CO

• Mid-IR CRDS for high precision and low drift analysis

• 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 <200 and <40 ppt for N2O and for CO. Drift at standard temperature and pressure (STP) over 24 hours is <100 ppt for N2O and for CO. Water correction software automatically reports dry gas mole fractions to help reduce research complexity and consumable costs.
