安捷伦7890 Agilent 7890玻璃球柱0.8m*4mm二氧化碳

药典二氧化碳：
碳氢化合物照气相色谱法(通则0521)测定供试品气体取本品,即得对照品气体取甲烷含量为0.0020%的气体(以氮气为稀释剂)。色谱条件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℃测定法精密量取供试品气体与对照品气体,分别注入气相色谱仪,在净化温度为360℃时测得的峰面积为相应空白值;精密量取供试品气体与对照品气体,分别注入气相色谱仪,测定峰面积,减去相应空白值后的峰面积为校正峰面积限度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%。

Pharmacopoeia carbon dioxide:

Hydrocarbons are measured using gas chromatography (General Rule 0521) to obtain the reference gas, which is a gas with a methane content of 0.0020% (using nitrogen as the diluent). Chromatographic conditions: Chromatographic column filled with glass balls (4mm × 0.8m, 80 mesh); The column temperature is 110 ℃; The inlet temperature is 110 ℃; The detector is a flame ionization detector, with a temperature of 120 ℃. The test gas and reference gas are accurately measured and injected into a gas chromatograph. The peak area measured at a purification temperature of 360 ℃ is the corresponding blank value; Accurately measure the test sample gas and the control sample gas, inject them into a gas chromatograph, measure the peak area, subtract the corresponding blank value, and the peak area is the corrected peak area limit. Calculate the corrected peak area using the external standard method, and the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
