HHO-III 净化装置/药典/二氧化碳/CO2的详细资料

型号:HHO-III Purification

应用:药典二氧化碳中碳氢化合物测定



2015版药典四部二氧化碳中碳氢化合物项方法描述如下:“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(0.8mX4mm,8 0目);柱温为110°C;进样口温度为110°C ; 检测器温度为120°C。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°C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,注人气相色谱仪,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%。”
这其中净化温度具体是指什么?是否因为药典方法描述不够详尽,实际是甲烷转化器之类的转化温度?

许多制药企业很困惑,以为净化温度就是甲烷转化炉,其实这是不对的。

Purification unit / Pharmacopoeia / CO2 / CO2 Details:

Model: HHO-III Purification
Application: Determination of hydrocarbons in carbon dioxide in Chinese Pharmacopoeia


The 2015 version of the Pharmacopoeia four carbon dioxide hydrocarbons method is described as follows: "take this product as a test sample; take a gas with a methane content of 0.0020% (with nitrogen as a diluent) as a control gas, by gas chromatography (General Rule 0521) Test, using a glass ball as a packing column (0.8mX4mm, 80 mesh); column temperature is 110 ° C; inlet temperature is 110 ° C; detector temperature is 120 ° C. Measure the gas and test The control gas is injected into the gas chromatograph, and the peak area measured at the purification temperature of 360 ° C is the corresponding blank value; the gas for the test sample and the control gas are taken, and the gas chromatograph is injected to determine the peak area, and the corresponding blank is subtracted. The peak area after the value is the corrected peak area. The hydrocarbon-containing compound (in terms of methane) shall not exceed 0.0020% by the external standard method.
What does the purification temperature mean? Is it because the Pharmacopoeia method description is not detailed enough, is it actually a conversion temperature such as a methanator?
Many pharmaceutical companies are confused, thinking that the purification temperature is a methane reformer. In fact, this is a big mistake.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd., relying on the R&D center of Hong Kong, China, successfully developed a purification device, which is original in China and is currently applying for patent protection.
