Measures N2O, CH4, CO2, NH3, and H2O

The Picarro G2508 gas concentration analyzer provides simultaneous, precise measurement of nitrous oxide (N2O), methane (CH4), carbon dioxide (CO2), ammonia (NH3) at parts-per-billion (ppb), and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for agriculture soil science, ecology, and emissions quantification.

  • Simultaneous and continuous measurement of N2O, CH4, CO2, NH3 and H2O
  • Parts-per-billion sensitivity for excellent rate-of-rise quantification
  • Rapid response time and continuous measurements provide data at high temporal resolution
  • Operates in open or closed systems and integrates easily with chamber systems
  • Water correction automatically reports dry gas mole fractions

Precision at 1 minute and 5 minutes is <10 and <5 ppb for N2O, <7 and <5 ppb for CH4, <300 and <200 ppb for CO2, and <3 and <1 ppb for NH3. Water correction software automatically reports dry gas mole fractions to help reduce research complexity and consumable costs.
