| 摘 要： | 针对高纯氘气中H2、HD与D2等氢同位素气体间不易分离分析的特点，以5A分子筛微填充石英毛细管色谱柱，在－95℃下对氢同位素进行分离，以气相色谱-脉冲放电氦离子化检测器对氢同位素进行分析。研究建立的H2、HD与D2等同位素气体测定方法精密度小于15%，最小检出摩尔分数为1×10－6。

| Abstract: | A new method for the determination of hydrogen isotopes by cryogenic gas chromatography was established. The analysis was carried out by cryogenic gas chromatography with pulsed discharge helium ionization detector on the capillary column of 5A molecular sieve. H2, HD and D2 mixtures was separated at －95 ℃. The detection limit is 1×10－6, and the precision of method is less than 15% for H2, HD and D2 . |
