A Revolution in Soil Flux Measurement

Download: New Application Note

Soil – Critical, but complicated. Greenhouse gas exchange between soil and the atmosphere is a critical step in the global nitrogen and carbon cycles, yet quantifying these fluxes is laborious. Picarro's G2508 analyzer radically simplifies soil flux studies by simultaneously measuring five gases to provide a complete picture of greenhouse gas soil emissions.

  • Measures all gases using precise cavity ring-down technology to offer excellent rate-of-rise quantification.
  • Rapidly recirculates gas through a soil chamber to provide a continuous record of the rate-of-rise at high temporal resolution.
  • Integrates easily with soil chambers -- No need to assemble and synchronize separate gas analyzers.
  • Field-proven, rugged platform measures fluxes without going back to lab. Optimize the experimental design immediately and get the right data the first time.
  • Couple the G2508 with the Picarro Soil Flux Processor for quick and easy calculation of soil fluxes.  Accelerate your science with this powerful and easy-to-use software tool. 

The G2508 is the latest Picarro analyzer that measures N2O concentration along with CH4, CO2, NH3 and H2O. The greenhouse gas concentrations are corrected for water vapor using methods validated by the atmospheric science community. For those that only need N2O, CH4, and H2O measurements, the G2308 is also available.
