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.
