這其中凈化溫度具體是指什么？是否因?yàn)樗幍浞椒枋霾粔蛟敱M，實(shí)際是甲烷轉(zhuǎn)化器之類的轉(zhuǎn)化溫度？

許多制藥企業(yè)很困惑，以為凈化溫度就是甲烷轉(zhuǎn)化爐，其實(shí)這是不對(duì)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.
