| Abstract: | This paper described a method for the analysis of CO、CO 2、residual benzene and inlet benzene in maleic anhydride production process using a single chromatograph with double columns operated by a six way exchange valve;the length of the stainless steel quantitative tube is 800mm. Four questions of quantitative tubes length,double columnsresistance,stationary phase and quantitative analytical method have been discussed.Chromatographic conditions:thermal conductivity detector;column temperature,60℃;column A activated charcoal and column B XE 60 |
