摘要
实验研究采用5A分子筛和氧化铝充填色谱柱分别在常温和低温(77K)下对D2中的O2、N2以及H2、HD等杂质进行定量分析测量,以建立1种准确实用的分析方法。研究结果表明,该方法对H2、HD的最低检测浓度可达(150-200)×10^-6,能够满足高纯氘制备过程中对杂质的定量分析要求。
A veracious and applicable quantitative analysis method of O2, N2 and H2, HD in high purity deuterium by the chromatogram columniation filled with 5A molecular sieve and alumina was researched and constituted at natural temperature and 77 K, respectively. Minimum detecting limit of the present method is (150-200)× 10^-6 for H2 and HD, and it can meet the need of quantitative analysis of the impurity during high purity deuterium preparation.
