碳氢化合物    取本品作为供试品；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（0.8m×4mm，80目）；柱温为110℃；进样口温度为110℃；检测器温度为120℃。量取供试品气体与对照气体，注入气相色谱仪，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，注入气相色谱仪，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%。
 

Take this product as the test sample for hydrocarbons; Take a gas with a methane content of 0.0020% (using nitrogen as the diluent) as the reference gas, and perform the gas chromatography test according to General Rule 0521. Use a chromatographic column (0.8m) filled with glass balls × 4mm, 80 mesh); The column temperature is 110 ℃; The inlet temperature is 110 ℃; The detector temperature is 120 ℃. Measure the test sample gas and control gas, inject them into a gas chromatograph, and the peak area measured at a purification temperature of 360 ℃ is the corresponding blank value; Measure the test sample gas and control gas, inject them into a gas chromatograph, measure the peak area, and subtract the corresponding blank value to obtain the corrected peak area. Calculated using the external standard method to correct peak area, the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
