氦中痕量 H2、D2组分的高精度气相色谱分析
Analysis of Trace Hydrogen and Deuterium in Helium by High-precision Gas Chromatograph
摘要
Abstract
It’s necessary to establish a high-precision analytical method of gas chroma-tography for achieving the rapid detection of trace components in fuel cycle system of fusion reactors. H 2 and D2 in high purity helium were separated with a handmade cryogenic capillary column of Al2 O3 ,and measured by discharge ionization detector. The results show that the detect limit of this method is less than 1 × 10 -8 ,retention time is less than 180 s,the relative standard deviation of area response of H 2 and D2 is not more than 1.0%,and the resolution of H 2 and D2 is above 1.0.This method is sensitive and fast,and can be applied to fuelling system and isotope separation system of fusion reactors for tritium safety analysis and accurate measurement.关键词
