摘　　要：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.
