| Abstract: |
| Trace hydrosphere was turned into hydrogen gas under specifically condition by LiAlH4 columniation. The generated hydrogen gas was mensurated exactly using chromatography with Zirconia detector to educe indirectly the content of trace hydrosphere in high pure gas. The results showed that this method had good selectivity, celerity, stabilization and repetition. In addition, the hydrogen detection by gas chromatography brought less molestation, wastage and time consumption. |
