The Greenhouse Gas GC is designed for the detection of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Depending upon the volume of the sample loop on the gas sampling valve, it can detect trace levels or high concentrations. It may be used for stack or ambient air monitoring, or in a plane for atmospheric air analysis. The chromatogram below was generated by a Greenhouse Gas GC with a 5mL sample loop.

The Greenhouse GC is not limited to CO2, CH4 and N2O. The FID-Methanizer detects hydrocarbons as well as CO and CO2 (as methane). The sensitive ECD detector responds to electronegative compounds, especially chlorinated, fluorinated, or brominated molecules like PCBs and pesticides. With a low-volume sample loop, the Greenhouse GC can be used to measure gases produced by bacterial metabolic processes and life cycles.
