空分裝置的要求出現(xiàn)了兩個(gè)較明顯的變化 :一是要求產(chǎn)液量大,氬產(chǎn)量高 ;二是要求氧氣終壓有所降低
對于含有氧氬組分混合氣體的分析一般采取氣相色譜法，以分子篩類吸附劑或高分子固定相為分離柱。但是由于氧氬極難分離，采用低溫柱或增加柱長等方式分離氧氬也存在靈敏度低等一些問題。

There are two significant changes in the requirements for air separation units: one is the requirement for a large liquid production and high argon production; The second requirement is to lower the final oxygen pressure
For the analysis of mixed gases containing oxygen and argon components, gas chromatography is generally used, using molecular sieve adsorbents or polymer stationary phases as separation columns. However, due to the extremely difficult separation of oxygen and argon, there are also some issues such as low sensitivity when using low-temperature columns or increasing column length to separate oxygen and argon.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a new gas chromatography method for the determination of oxygen and argon in air separation units. The method uses an area external standard for quantitative analysis, and the results show that the argon content is accurate and reliable.
Name: Special Column for Oxygen and Argon Separation in Air Separation Unit
Fixed phase: Dedicated
Specification: 3m * 1/8
