Quantitative analysis of oxygen, nitrogen, hydrogen and hydrogen deuteride in high-purity deuterium by gas chromatography

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 Å molecular sieve and alumina as column packing materials respectively. The minimum detection limit was 150–200 ppm for hydrogen and hydrogen deuteride. The method is suitable for quantitative analysis of impurities during high-purity deuterium preparation.
