【Abstract】 An hydrogen sample was described to play an important role in gas quantitative analysis and tritium chemistry field,which was less than natural deuterium abundant and called depleted deuterium.By selection of separative methods,adsorbents,column length,column radius and operative parameters,it was prepared for hydrogen sample with depleted deuterium through one dimension of cryogenic chromatography separation technology and no-carrier gas,based on the design of preparation process.This method can be used to prepare the hydrogen sample with depleted deuterium in one hour,based on the raw material of high grade hydrogen with deuterium abundant about 1.4×10-4.更多还原
