Gas chromatography was used to analyze and detect chlorosilane in trichlorosilane. The results show that selecting programmed heating can better separate various chlorosilanes. When the carrier gas flow rate is 20ml/min and the reference flow rate is 30ml/min, the sensitivity of the method is the highest; Accurate characterization of chlorosilane in trichlorosilane was carried out using standard substances and the boiling point law of homologues; By using SiCl4 as the standard substance and calculating the relative correction factors, it was found that the relative correction factors of various chlorosilanes were close to 1; The area percentage method was used for convenient, accurate, and rapid quantitative analysis of various chlorosilanes, with a relative standard deviation of less than 3%.
