气相色谱仪检测溶解气H_2、He最佳观测条件的选择

Selection of the optimum observation condition for detecting dissolved gases of H_2 and He with gas chromatograph

通过色谱柱、固定相以及载气流速的选择性实验 ,提高了气相色谱仪在观测地下水中H2 、He分离效能和检测效能。本文对此作介绍 ,以期对使用气相色谱仪进行地下水H2 。

Selective experiments have been made concerning chromatographic colomn, fixed phase and flow rate of carrier gas. Based on the results of these experiments, the separation efficiency of H 2 and He in ground water observations using gas chromatograph can be improved. The results are useful to the stations observing H 2 and He in ground water using gas chromatograph.
