Single Sample Analysis of N2-N2O-CO2-A-O2 Mixtures by Gas Chromatography

A method is described for quantitatively analyzing gaseous mixtures of N2-N2O-CO2-A-O2 by gas chromatography, using 3 columns of molecular sieve material at elevated, ambient, and sub-ambient temperatures. With simple modifications, the analysis time of 5 minutes can be reduced.
