HH-CH4-GC便携式甲烷转化炉 氧药典标准医用氧中CO2，CO测定

2021年2月6日，国家药典委员会修改公布了“关于氧国家药品标准草案”其中对医用氧的纯度及氧中痕量一氧化碳、二氧化碳、水分的含量及其检测方法都做了新规定。

新规在《中国药典》2020 年版二部 XGB2021-061条（医用氧技术指标：氧≥99.5% 、一氧化碳<0.0005、二氧化碳＜0.03%、水分含量＜0.0067%）于2022年5月22日实施。

浩瀚色谱（山东）应用技术开发有限公司，，研发便携式气相色谱仪，面积外标法测定氧药典标准医用氧中CO2，CO的含量，柱效高，分离好，结果满意。

Determination of CO2 and CO in Oxygen Pharmacopoeia Standard Medical Oxygen
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.
