Short summary
We present a method for the determination of greenhouse gases (CH4, CO2, N2O) using a chromatographic system with a barrier ion discharge detector (BID) and a Carboxen 1010 capillary column. The system omits the need for an electron capture detector (ECD) containing radiogenic components for N2O analysis and a flame ionisation detector (FID) with a methaniser for CO2 samples. This simplification reduces analytical costs, facilitates instrument maintenance and improves measurement robustness.
