药典二氧化碳碳氢化合物测定 详细信息：

名称：玻璃球为填料的色谱柱

粒度：80目

规格：0.8m*4mm

型号：HH-BLQ

应用：药典二氧化碳中碳氢化合物测定

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%。

Determination of Carbon Dioxide and Hydrocarbons in Pharmacopoeia
Determination of Carbon Dioxide and Hydrocarbons in Pharmacopoeia Details:

Name: Chromatographic Column with Glass Ball as Filler

Granularity: 80 mesh

Specification: 0.8m*4mm

Model: HH-BLQ

Application: Determination of hydrocarbons in pharmacopoeia carbon dioxide

For hydrocarbons, this product is used as the test gas, and the gas with a methane content of 0.0020% (with nitrogen as the diluent) is used as the control gas. According to the gas chromatography (general rule 0521) test, a column filled with glass balls ( 4mm×0.8m, 80 mesh); the column temperature is 110°C; the inlet temperature is 110°C; the detector is a flame ionization detector, and the temperature is 120°C. Measure the test gas and control gas and inject them into the chromatograph. The peak area measured when the purification temperature is 360°C is the corresponding blank value; measure the test gas and control gas and inject them into the chromatograph to determine the peak area and reduce The peak area after removing the corresponding blank value is the corrected peak area. According to the external standard method to calibrate the peak area, the hydrocarbon (calculated as methane) shall not exceed 0.0020%.
