毛细管柱测定CO2中碳氢化合物

规格：30m*0.53mm

型号：HH-THC-30

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%。”

随着气相色谱仪的发展，许多制药企业购置的是毛细管进口系统的气相色谱，因此填充柱接不上，需要改造仪器，十分麻烦，滕州市浩瀚色谱仪器技术服务有限公司，，研发毛细管柱测定CO2中碳氢化合物，安装方便，仪器无需改造，效率高，结果满意。







Determination of Hydrocarbons in CO2 by Capillary Column
Determination of Hydrocarbons in CO2 by Capillary Columns

Specification: 30m*0.53mm
Model: HH-THC-30
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.
With the development of gas chromatographs, many pharmaceutical companies purchase gas chromatography of capillary inlet systems, so the filling column can not be connected, and it is very troublesome to modify the instrument. Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times. The development of capillary column for the determination of hydrocarbons in CO2 is easy to install, the instrument does not need to be modified, the efficiency is high, and the results are satisfactory.
