玻璃球色谱柱药典二氧化碳
玻璃球色谱柱药典二氧化碳 详细信息：

名称：玻璃球柱
规格：1m*1/8（80目，安捷伦，岛津，赛默飞，瓦里安，布鲁克，PE等英制尺寸）
型号：HH-BLQ
应用：中国药典2020版--二氧化碳中碳氢化合物的测定

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%。

Glass bulb chromatographic column pharmacopoeia carbon dioxide
Pharmacopoeia Carbon Dioxide for Glass Ball Chromatography Column Details:

Name: Glass Ball Column
Specifications: 1m*1/8 (80 mesh, Agilent, Shimadzu, Thermo Fisher, Varian, Brook, PE and other inch sizes)
Model: HH-BLQ
Application: Chinese Pharmacopoeia 2020 Edition-Determination of Hydrocarbons in Carbon Dioxide

Hydrocarbons are determined according to gas chromatography (General Principle 0521). Take this product as the test sample gas, that is, the reference sample gas should be a gas with a methane content of 0.0020% (with nitrogen as a diluent). Chromatographic conditions use a chromatographic column filled with glass balls (4mm×0.8m, 80 mesh); the column temperature is 110℃; the temperature of the injection port is 110℃; the detector is a flame ionization detector, and the temperature is 120℃. The method is precise. Measure the test gas and reference gas and inject them into the gas chromatograph respectively. The peak area measured when the purification temperature is 360°C is the corresponding blank value; accurately measure the test gas and reference gas and inject them into the gas chromatograph. The peak area is determined by the instrument, and the peak area after subtracting the corresponding blank value is the calibrated peak area limit. The peak area is calculated by the external standard method, and the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
