摘要
氢同位素气体分析在氚处理工艺及聚变堆燃料循环系统中有着非常重要的应用。由于同位素具有相同的化学性质,其分析只能利用其物理性质的微小差别来实现,带有低温分离柱的气相色谱仪是分析氢同位素的重要方法之一,而近年来在研究应用方面取得重要进展的微气相色谱有望大幅缩短分析时间,实现在线分析,具有潜在的重要应用前景。本文阐述了气相色谱分析氢同位素色谱柱材料、检测器、载气、定量方法等方面研究现状,并对存在的问题及发展方向作了讨论。
In the tritium processing system and fuel cycle system of fusion reactors,analysis of hydrogen isotopes is very important.Because their chemical properties are the same,to analyze hydrogen isotopes can only be completed by using their minute difference in physical properties.Gas chromatograph（GC）with cryogenic separation column is one of the best methods for the analysis of hydrogen isotopes.In recent years,significant progress of micro GC has been made.It is expected to shorten analysis time and realize on-line analysis,with promising potential for application.In this review,the materials of chromatographic column,detector,carrier gas and quantitative method are summarized and analyzed,and the application and outlook are also reviewed.
