摘要：

The impurity composition of arsine is studied by gas chromatography-mass-spectrometry. Impu-rities of permanent gases; carbon dioxide; hydrides; saturated, unsaturated, and aromatic hydrocarbons C-1-C-6; halogenated hydrocarbons; sulfur compounds; and arsine and diarsine alkyl derivatives are determined. The impurity level of high-purity arsine is 10(-6)-10(-5) vol %. Impurity concentrations in arsine after synthesis and in the fractions extracted in the course of its rectification are rather high and lie in the range 10(-6)-0.1 vol %. The limits of detection for impurities are 2 x 10(-7)-2 x 10(-4) vol %.
