| The Chromium Analytical Technique for Hydrogen Isotopes |
| The chromium reduction technique is an extremely simple and quantitative method for converting H in micro-water and in a variety of organic molecules into H2. The metal chromium has an advantage over U and Zn in that the hydrogen in micro-water samples and many hydrogen-bearing compounds can be reduced to H2，In this paper an analytical technique using chromium as a reducing matter is presented for the determination of the hydrogen isotope composition in micro-water samples and hydrogen-bearing compounds. The technological process of the chromium reduction method is simple, accurate (precision ±2‰)，and rapid（10 minutes for each micro-water sample) for hydrogen isotope composition in micro water samples and organic molecules. It can therefore be used in a wide variety of analytical fields, including hydrogen isotope analyses of micro-water samples and hydrogen-bearing organic molecules. |
