This part of this International Standard describes a gas chromatographic method for the quantitative
determination of the content of nitrogen, carbon dioxide and C1 to C5 hydrocarbons individually and
a composite C6+ measurement, which represents all hydrocarbons of carbon number 6 and above in
natural gas samples. It is applicable to the analysis of gases containing constituents within the working
ranges given in Table 1.
