尽管氧氩混合气体的分析方法种类较多,而且根据待测组分含量的大小及杂质种类而选用不同的分析方法,一般可分为直接测定法和间接测定法。直接测定法为直接测定出氧气的含量;间接测定法为测定氧气中氩等组分的含量,再利用差减法计算出氧的含量。但是现有的这些分析方法均不够理想。对于含有氧氩组分混合气体的分析一般采取气相色谱法,以分子筛类吸附剂或高分子固定相为分离柱。但是由于氧氩极难分离,采用低温柱或增加柱长等方式分离氧氩也存在灵敏度低等一些问题。
浩瀚色谱(山东)应用技术开发有限公司研究主要是想找到一种专用固定相在气相色谱法分析氧氩混合气体时,直接进样分析即可分析O2,AR,N2,并且建立气相色谱法分析含氧氩混合气体中氩组分含量的分析方法。

Although there are many types of analysis methods for oxygen-argon mixed gas, and different analysis methods are selected according to the content of the components to be measured and the types of impurities, they can generally be divided into direct measurement methods and indirect measurement methods. The direct measurement method is to directly measure the oxygen content; the indirect measurement method is to measure the content of argon and other components in oxygen, and then use the subtraction method to calculate the oxygen content. However, these existing analysis methods are not ideal. For the analysis of mixed gas containing oxygen and argon components, gas chromatography is generally adopted, and molecular sieve adsorbent or polymer stationary phase is used as the separation column. However, because oxygen and argon are extremely difficult to separate, there are some problems such as low sensitivity when separating oxygen and argon by means of low temperature column or increasing column length.
The research of Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. is mainly to find a special stationary phase to analyze O2, AR, N2 by direct injection analysis when gas chromatography analysis of oxygen and argon mixture, and to establish a gas chromatography analysis method Method for analyzing the content of argon components in mixed gas containing oxygen and argon.
