Abstract:

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．
