A reliable and useful gas chromatography method for quantitative analysis of oxygen and
nitrogen at room temperature and hydrogen and hydrogen deuteride at 77 K in high-purity
deuterium was developed using 5 A˚ molecular sieve and alumina as column packing
materials respectively. The minimum detection limit was 150e200 ppm for hydrogen and
hydrogen deuteride. The method is suitable for quantitative analysis of impurities during
high-purity deuterium preparation.
