2015年版中国药典二氧化碳玻璃球柱
2015年版中国药典二氧化碳玻璃球柱 详细信息：

名称：药典二氧化碳专用柱

规格：0.8m*4mm

粒度：80Mesh

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；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%。

2015 Chinese Pharmacopoeia Carbon Dioxide Glass Sphere
2015 Chinese Pharmacopoeia Carbon Dioxide Glass Ball Column Details:

Name: Pharmacopoeia special column for carbon dioxide

Specification: 0.8m*4mm

Granularity: 80Mesh

Model: HH-BLQ

Application: Determination of hydrocarbons in carbon dioxide in Pharmacopoeia



Hydrocarbons Take this product as the test sample; take the gas with a methane content of 0.0020% (with nitrogen as the diluent) as the control gas, and test according to the gas chromatography (General Rule 0521), using a glass ball as the packing column (0.8 m×4mm, 80 mesh); column temperature is 110℃; injection port temperature is 110℃; detector temperature is 120℃. Measure the test gas and control gas and inject them into the gas 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 gas chromatograph to determine the peak area , The peak area after subtracting the corresponding blank value is the corrected peak area. According to the external standard method to calibrate the peak area, the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
