Using the gas scanning method, under selected working conditions, the gas in the gas phase is passed through a chromatograph to separate the non-condensable gas (abbreviated as non-condensable gas) into its components. The amount of non-condensable gas is calculated by the external standard method using thermal conductivity detector (TCD) detection. In the type of preservative products, the only gas with no initial content is variable gas, and other gases are not normally analyzed. The gas cylinders and temperature calibration between the two phases do not need to be properly calibrated, and the results are reported. 4.2 Reagents
