- Scope
- This part gives the quantitative determination of He, H2, O2, N2, CO2 and C1 in natural gas by two packed columns. To C8 Gas Chromatography of Hydrocarbons. This method is suitable for laboratory and on-line analysis and detection, and can analyze gases whose component mole fractions are within the range of Table 1, but cannot contain liquid hydrocarbons. This range does not represent the limit of detection, but rather the limit of the precision specified by the method. This method is applicable even though one or more components may not be present in the sample. This section is only used in conjunction with Parts 1 and 2 of GB/T 27894. The scope of application is slightly
