This part of ISO 6974 describes a gas chromatographic method for the quantitative determination of natural gas
constituents using a three-column system. This method is applicable to natural gases of limited range, on-line and automatically calibrating on a regular basis for gas samples not containing any hydrocarbon condensate and/or water. It is applicable to the analysis of gases containing constituents within the mole fraction ranges. These ranges do not represent the limits of detection, but the limits within which the stated precision of the
method applies. Although one or more components in a sample may not be detected present, the method can still be applicable.
This part of ISO 6974 is only applicable if used in conjunction with parts 1 and 2 of ISO 6974.
