Determination of Benzene,Toluene and Xylene of Paint Using GC with Capillay Column

A simple,rapid and accurate gas-chromatographic method for the determination of benzene,toluene and xylene was studied.The analysis was made by using HP-5 capillary column and FID detector.We could be gotten the contents of benzene,toluene and xylene by only one injection.All components and internal standard were separated in 185 mins.The results with good linearities(r=0999 3,0999 8 and 0999 2)were obtained.The coefficients of variation were 078%,060% and 068%.The recoveries of the method were 981%-1011%,979%-995% and 980%-1002%.
