| 摘 要： | 本文通过对SF_6、CF_2ClBr、CF_2Br_2、CF_2Cl_2四种气体的色谱分析研究,探讨了它们在电子捕获检测器、5A分子筛柱上的响应特性,并根据煤矿井下实际,最终优选出SF_6和CF_2ClBr两种示踪气体。同时实验研究了分析SF_6和CF_2ClBr示踪气体的色谱操作条件,提出了最佳色谱操作条件。

| Abstract: | Based on chromatographic analysis of 4 types of gases SF6, CF2ClBr, CF2Br2 and CF2Cl2, the gas response properties are discussed in the electron capture detector and the 5 A sieve sorbent column. According to the actual situation of underground coal mines, SF6 and CF2ClBr are finally chosen, and the chromatographic operation conditions of the two gases are analysed through experiments. And the best chromatographic operation condition is determined. |
