Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. used capillary column and GC-790 chromatograph with flame photometric detector to conduct tests. After fixing the column temperature and split ratio, orthogonal test design was used to investigate the influence of detector temperature, hydrogen flow, air flow and sample injection volume on thiophene peak response (peak area), and find out the best operating conditions for * * *, A method for the determination of trace thiophenol in industrial pure benzene by capillary column gas chromatography was established. The relative standard deviation of the method is less than 3% and the relative error is less than 1%.
