Hydrocarbon is taken as the test gas, and a gas with a methane content of 0.0020% (with nitrogen as a diluent) is used as a control gas, and gas chromatography (General Rule 0521) is used to test the column with glass spheres as a filler ( 4mm × 0.8m, 80 mesh); column temperature is 110 ° C; inlet temperature is 110 ° C; detector is flame ionization detector, temperature is 120 ° C. The test gas and the control gas are measured and injected into the chromatograph. The peak area measured at the purification temperature of 360 ° C is the corresponding blank value; the gas for the test sample and the control gas are taken, injected into the chromatograph, and the peak area is measured and reduced. The peak area after the corresponding blank value is the corrected peak area. According to the external standard method, the hydrocarbon content (in terms of methane) should not exceed 0.0020%.
