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%。

浩瀚色谱研制的玻璃球色谱柱，柱效高，分离好，和岛津，赛默飞，瓦里安，布鲁克，pe，磐诺，福立，北分瑞利等仪器，能实现互联互通，结果满意。

Hydrocarbons: This product is used as the test gas, and a gas with a methane content of 0.0020% (diluted with nitrogen) is used as the control gas. The gas chromatography method (General Rule 0521) is used for testing, and a chromatography column (4mm × 0.8m, 80 mesh) filled with glass spheres is used; The column temperature is 110 ℃; The inlet temperature is 110 ℃; The detector is a flame ionization detector with a temperature of 120 ℃. Measure the test gas and control gas, inject them into the chromatograph, and measure the peak area at a purification temperature of 360 ℃ as the corresponding blank value; Measure the test gas and control gas, inject them into the chromatograph, measure the peak area, and subtract the corresponding blank value to obtain the corrected peak area. According to the external standard method, the corrected peak area should not exceed 0.0020% for hydrocarbons (calculated as methane).
The glass sphere chromatography column developed by Haohan Chromatography has high column efficiency and good separation. It can be interconnected with instruments such as Shimadzu, Thermo Fisher Scientific, Varian, Brooke, PE, Panno, Fuli, and Beifen Raleigh, and the results are satisfactory.
