提供完整的分析方案

碳氢化合物 取本品作为供试品气体，取甲烷含量为0.0020%的气体(以氮气为稀释剂)作为对照气体，照气相色谱法(通则0521)试验，用玻璃球为填料的色谱柱(4mm×0.8m，80目)；柱温为110℃；进样口温度为110℃；检测器为火焰离子化检测器，温度为120℃。量取供试品气体与对照气体，注入色谱仪，在净化温度为360℃时测得的峰面积为相应空白值；量取供试品气体与对照气体，注入色谱仪，测定峰面积，减去相应空白值后的峰面积为校正峰面积。按外标法以校正峰面积计算，含碳氢化合物(以甲烷计)不得过0.0020%。

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%.
