Gasmet, the gas monitoring equipment manufacturer from Finland, has demonstrated that its FTIR gas analyser is the ideal device for measuring greenhouse gases (GHG) from soil.
Carbon Dioxide (CO2), Methane (CH4) and Nitrous Oxide (N2O), released from soils into the atmosphere are primarily biogenic by origin and represent a major source of GHGs. Thanks to the FTIR’s portable, robust and battery-powered features, reliable onsite analysis can be carried out to measure GHG soil fluxes.
One of the most widely used techniques to measure soil fluxes is a chamber method in which an open-bottom soil chamber is placed on the ground and the concentration changes per chamber footprint area are measured over time. The soil chamber can be integrated with a Gasmet gas analyser, forming a closed-loop system in which the gas sample is circulated through the analyser back to the chamber.
