1 Scope

This section GB/T 27894 gives the determination of hydrogen gas with three quantitative capillary column, helium, oxygen, nitrogen, carbon dioxide and C1 to C8 hydrocarbon content of a gas chromatography. This method is suitable for analysis within the range of mole fractions given in Table 1 gas group Min. These ranges do not represent the detection limit, and that the use of the method in this range to achieve a predetermined precision. While the sample will have a Or more of the components can not be detected, but this method can still apply. In conjunction with Part 2 GB/T 27894 This part of the GB/T 27894 Part 1 and GB/T 27894 in. The method is also suitable for the analysis of substitute natural gas.
