Greenhouse Gas Analyser
Elementar isoFLOW GHG
The iso FLOW GHG uses cryogenic pre-concentration to enable the high precision isotope analysis of 13C-CO2, 15N-N2O, and 13C-CH4, which are found at trace concentrations in the atmosphere. Our bespoke configuration also allows the measurement of 15N-N2 via a 7ul sub-sampling loop and a reduced Cu furnace at 600oC for the elimination of NOx and oxygen. The automated chemical trapping and gas chromatography techniques utilized by the iso FLOW GHG allows the trace greenhouse gas to be isolated from other atmospheric constituents and delivered into the isotope ratio mass spectrometer without isotopic fractionation for the highest sensitivity of these low concentration gases. We are able to analyse both natural abundance and enriched samples supplied in 12 mL exetainer vials with our fully automated autosampler.
