Annotation of standard text ČSN EN ISO 6974-5 (385506):
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 (in mole fraction, %): Nitrogen, N2 (0,1-22); Carbon dioxide, CO2 (0,05-15); Methane, CH4 (34-100); Ethane, C2H6 (0,1-23); Propane, C3H8 (0,05-10); iso-Butane, i-C4H10 (0,01-2,0); n-Butane, n-C4H10 (0,01-2,0); neo-Pentane, neo-C5H12 (0,005-0,35); iso-Pentane, i-C5H12 (0,005-0,35); n-Pentane, n-C5H12 (0,005-0,35); Hexanes +, C6+ (0,005-0,35)
