Scope

This part of GB/T 27894 provides a gas chromatographic method for quantitatively analyzing the composition of natural gas using a three-column system. This method is suitable for a certain range of natural gases, and it can be used to automatically calibrate online conventional gas samples that do not contain any hydrocarbon condensate or water. This method is applicable to gas components with a mole fraction within the range specified in Table 1. These ranges do not represent the detection limit, but rather indicate that the specified accuracy can be achieved using this method within this range. Even if one or more components in the sample cannot be detected, this method can still be applied.
This part should be used in conjunction with Part 1 and Part 2 of GB/T 27894.
