GB/T 27894.4-2012 Natural gas—Determination of composition with defined uncertainty by gas chromatography—Part 4:Determination of nitrogen,carbon dioxide and C1 to C5 and C+6 hydrocarbons for a laboratory and on-line measuring system using two columns
Abstract
This part of GB/T 27894 provides a gas chromatography method for quantitatively determining the composition of natural gas using a two-column system. This method is suitable for detection in laboratories and online measurement systems, and can analyze the content of gas components within the mole fraction range given in Table 1. These ranges do not represent the detection limit, but indicate that the method can achieve the specified accuracy within this range. Although one or more components in the sample may not be detected, the method is still applicable.
This part is used in conjunction with Part 1 and Part 2 of GB/T 27894.
