隨著氣相色譜儀的發(fā)展，許多制藥企業(yè)購置的是毛細(xì)管進口系統(tǒng)的氣相色譜，因此填充柱接不上，需要改造儀器，十分麻煩，滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，與時俱進，研發(fā)毛細(xì)管柱測定CO2中碳?xì)浠衔?/strong>，安裝方便，儀器無需改造，效率高，結(jié)果滿意。







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.
