    Abstract
  • The accuracy of hydrogen isotope analysis results needs a kind of working standard gas as a prerequisite.The steel-bottled hydrogen gas can be used as the working standard gas to measure the stability and the error of the instrument during the analyses of hydrogen isotopes.The hydrogen isotope fractionates greatly during the experiment,making the calibration of the standard working gas more important.Based on the theoretical results calculated from the hydrogen isotopic fractionation equilibrium equation of the H2-H2O(ι)system,the calibration of the working standard gas has been carried out in the experimental analysis of the hydrogen isotope of the natural water.The results are consistent with those analyzed by the Cr reduction method under high temperature conversion conditions.Two kinds of national standard water,Gbw04401 and Gbw04403,are used to testify the effectiveness of the calibration method.The results show that both the accuracy and the precision of this calibration method accord with the demands,and thus it can be used for hydrogen isotope analysis.
