为满足聚变堆氘氚燃料循环工艺气体中痕量氢组分的特殊检测分析要求,需建立快速、高精度的在线气相色谱检测分析方法。本研究采用GOW-MAC 816型高精度气相色谱仪,以高纯氦气作为载气,通过柱参数为15 m×0.53 mm×50μm的5A分子筛柱,在柱温为40℃、载气流速为15mL/min的条件下,对He中不同浓度的H2 In order to meet the special detection and analysis requirements of trace hydrogen components in the deuterium and tritium fuel cycle process gas of fusion reactor, a rapid and accurate on-line gas chromatography detection and analysis method needs to be established. In this study, a GOW-MAC 816 high-precision gas chromatograph was used with high-purity helium as a carrier gas and passed through a 5A molecular sieve column with a column parameter of 15 m × 0.53 mm × 50 μm at a column temperature of 40 ° C. The carrier gas flow rate was 15mL / min conditions, different concentrations of He in H2
