5Å分子筛色谱柱用于定量气体中的O2、N2、CH4、CO含量。实际应用中,由于5Å分子筛色谱柱吸潮,4种气体组分保留时间往往提前,甚分离度小于1. 5,尤其影响氧气峰的峰形,氧含量测定准确度降低。为此,从调整阀切时间和延长5Å分子筛色谱柱方面入手进行试验,以探寻解决问题的办法。经过一系列的试验和优化,终使煤气中的O2、N2、CH4、CO在5Å分子筛色谱柱内达到了更好的分离效果,尤其是使氧含量测定的准确度得到了提升。

Specifications: 1m*1/8
Model: 5Å molecular sieve column

5Å molecular sieve column is used to quantify O2, N2, CH4, CO content in gas. In practical applications, due to the moisture absorption of the 5Å molecular sieve column, the retention times of the four gas components are often advanced, and even the resolution is less than 1.5, which especially affects the peak shape of the oxygen peak and reduces the accuracy of oxygen content determination. Therefore, experiments were carried out by adjusting the valve cut time and extending the 5Å molecular sieve chromatographic column to find a solution to the problem. After a series of experiments and optimizations, the O2, N2, CH4, and CO in the gas finally achieved a better separation effect in the 5Å molecular sieve chromatographic column, especially the accuracy of the oxygen content determination was improved.
