HHO-IIIPurification 2020中国药典二氧化碳检测专用净化装置

名称：药典二氧化碳（CO2）净化装置

型号：HHO-III Purification device

应用：2020版药典二氧化碳中碳氢化合物测定  气相色谱法

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%。

浩瀚色谱（山东）应用技术开发有限公司，研发2020版药典二氧化碳中碳氢化合物检测专用净化装置，在安捷伦7890B，岛津GC-2010，GC-2014，赛默飞，瓦里安，PE等气相色谱仪上安装，调试，效果满意，受到用户的好评。

2020 Chinese Pharmacopoeia special purification device for carbon dioxide detection
2020 Chinese Pharmacopoeia special purification device for carbon dioxide detection Details:

Name: Pharmacopoeia carbon dioxide (CO2) purification device

Model: HHO-III Purification device

Application: Pharmacopoeia 2020 Determination of Hydrocarbons in Carbon Dioxide Gas Chromatography

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, according to the gas chromatography (General Rule 0521) test, use a glass ball as a filler column (0.8 m×4mm, 80 mesh); the column temperature is 110°C; the inlet temperature is 110°C; the detector temperature is 120°C. Measure the test gas and reference gas, inject them into a gas chromatograph, and measure the peak area when the purification temperature is 360 °C as the corresponding blank value; Measure the test gas and reference gas, inject them into a gas chromatograph, and measure the peak area , the peak area after subtracting the corresponding blank value is the corrected peak area. Calculated based on the corrected peak area according to the external standard method, the hydrocarbon content (calculated as methane) should not exceed 0.0020%.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed a special purification device for the detection of hydrocarbons in carbon dioxide in the 2020 edition of the Pharmacopoeia. The chromatograph is installed and debugged, and the effect is satisfactory, which is well received by users.
