| 摘 要： | 本文介绍一种新型气相色谱固定相——碳分子筛(KMS),其最大的优点是在常温下,单柱即可同时分离分析H_2、O_2、N_2、CO、CH_4、CO_2六种混合气体,柱子的保留值重现性好,峰形对称,柱效高。本文求得了在H_2和Ar作载气时KMS对上述六种气体的定性定量特性,配气的定量结果总的平均相对误差为3.67％。同时这种碳分子筛原料易得,制作简单,成本便宜。

| Abstract: | A new type of carbon molecular sieve (KMS) is introduced as a new chromatographic stationary phase into analysis of permanent gases. The main advantage of this new stationary phase is that a mixture of H_2, O_2, N_2, CO, CH_4, and CO_2 can be separated and determined by a single column at normal temperature, with good reproducibility, symmetric shape of peaks and high efficiency of the column. The qualitative and quantitative characteristics of the new stationary phase are investigated, with hydrogen or argon as the carrier gas. The average relative error of the determined value for blended samples is 3.67%. |
