毛细管柱测定药典二氧化碳
毛细管柱测定药典二氧化碳 详细信息:

规格:30m*0.53mm

型号:HH-THC-30



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%。

中华人民共和国药典二氧化碳中碳氢化合物的测定采用的是玻璃球0.8m*4mm的填充柱,然而许多制药企业配置的是毛细管系统,因此填充柱不适应了,否则要对仪器改造,费时费力,效率低。

滕州市浩瀚色谱仪器技术服务有限公司,,研发出毛细管测定药典二氧化碳中碳氢化合物,与填充柱互相配合,效率高,结果满意。

Capillary Column Determination of Pharmacopoeia Carbon Dioxide Details:

Specification: 30m*0.53mm
Model: HH-THC-30


Hydrocarbon is taken as the test gas, and a gas with a methane content of 0.0020% (with nitrogen as a diluent) is used as a control gas, and gas chromatography (General Rule 0521) is used to test the column with glass spheres as a filler ( 4mm × 0.8m, 80 mesh); column temperature is 110 ° C; inlet temperature is 110 ° C; detector is flame ionization detector, temperature is 120 ° C. The test gas and the control gas are measured and injected into the chromatograph. 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, injected into the chromatograph, and the peak area is measured and reduced. The peak area after the corresponding blank value is the corrected peak area. According to the external standard method, the hydrocarbon content (in terms of methane) should not exceed 0.0020%.

The determination of hydrocarbons in carbon dioxide in the Pharmacopoeia of the People's Republic of China uses a packed column of glass spheres of 0.8m*4mm. However, many pharmaceutical companies are equipped with capillary systems, so the packed columns are not suitable, otherwise it will take time and effort to renovate the instrument. low efficiency.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. has been advancing with the times to develop a capillary method for the determination of hydrocarbons in the Pharmacopoeia carbon dioxide, which cooperates with the packed column, with high efficiency and satisfactory results.
