Determination of CO2 and CO in Oxygen Pharmacopoeia Standard Medical Oxygen Details:

Name: Portable Methane Reformer
Model: HH-CH4
Application: Determination of trace carbon monoxide and carbon dioxide in Pharmacopoeia oxygen

On February 6, 2021, the National Pharmacopoeia Committee revised and published the "Draft National Drug Standard for Oxygen", which made the latest regulations on the purity of medical oxygen, the content of trace carbon monoxide, carbon dioxide, and moisture in oxygen and its detection methods.

The new regulations are implemented on May 22, 2022 in Article XGB2021-061, Part II of the 2020 edition of the Chinese Pharmacopoeia (Technical indicators of medical oxygen: oxygen ≥ 99.5%, carbon monoxide < 0.0005, carbon dioxide < 0.03%, moisture content < 0.0067%).

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and develops a portable gas chromatograph. The area external standard method is used to determine the content of CO2 and CO in Oxygen Pharmacopoeia standard medical oxygen. The column efficiency is high, the separation is good, and the results are satisfactory.
