Scope
This section presents a gas chromatography method for quantitatively determining He, H2, O2, N2, CO2, and C1 to C8 hydrocarbons in natural gas using two packed columns. This method is suitable for laboratory and online analysis and detection, and can analyze gases with a molecular fraction within the range specified in Table 1, but it cannot contain liquid hydrocarbons. This range does not represent the detection limit, but rather the range of precision specified by this method. Even if one or more components may not be present in the sample, the method can still be applied.
This section is only used in conjunction with Parts 1 and 2 of GB/T 27894.
