%X In this paper an analytical method of the Membrane ExtractionMicrotrap/Gas ChromatographyMass Spectrometer(MEMT/GCMS)for determination of trace pollutants benzenesubstituted from a small volume of water sample was researched.The experimental results showed that the recoveries of benzene,toluene,m,pxylene and oxylene were 89%99%,and the RSDs of them were 1.16%360%,and the sampling volumes of them were 0.0052.00ml,and the experimental concentrations of them mainly were 0.560g/L,and the low detection limits of them were 0.050.1ng/g.The application results also showed that the MEMT/GCMS method was a very promising,easy to handle,low cost,no solvent required,detection limits at ppt level when a small volume of water sample was analysed and measured.
