空分裝置中氧、氬混合氣體的測定專用毛細管柱 詳細信息：

空分裝置在運行過程中需要準確分析出過冷器純氮氣、下塔壓力氮氣、上塔工藝氧氣、液空純度等工藝段中的各組分含量，這其中主要是含有氧、氬成分的混合氣體。這對于及時掌握工藝設備生產狀況、清楚了解物流的平衡參數，從而使裝置安全平穩正常運行具有極其重要的意義。盡管氧氬混合氣體的分析方法種類較多，而且根據待測組分含量的大小及雜質種類而選用不同的分析方法，一般可分為直接測定法和間接測定法。直接測定法為直接測定出氧氣的含量；間接測定法為測定氧氣中氬等組分的含量，再利用差減法計算出氧的含量。但是現有的這些分析方法均不夠理想。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。

Special capillary column for determination of oxygen and argon mixed gas in air separation plant
Dedicated capillary column for the determination of oxygen and argon mixed gas in an air separation unit Details:

During the operation of the air separation unit, it is necessary to accurately analyze the content of each component in the process section of the subcooler pure nitrogen, lower column pressure nitrogen, upper column process oxygen, and liquid air purity, among which are mainly oxygen and argon components. mixed composition. This is of great significance for timely grasp of the production status of process equipment and a clear understanding of the balance parameters of logistics, so as to ensure the safe, stable and normal operation of the device. Although there are many types of analysis methods for oxygen and argon mixed gases, 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. Direct measurement method is to directly measure the content of oxygen; 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 gases containing oxygen and argon components, gas chromatography is generally adopted, with molecular sieve adsorbents or polymer stationary phases as separation columns. However, because oxygen and argon are extremely difficult to separate, the use of low-temperature columns or increasing column length to separate oxygen and argon also has some problems such as low sensitivity.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. researched a special capillary column that can react with oxygen to achieve high efficiency when analyzing oxygen-argon mixed gas by gas chromatography, and established gas chromatography to analyze the argon group in oxygen-containing argon mixed gas. Analysis method of sub-content.
