Established a gas chromatography/mass spectrometry direct analysis method of benzene series in the adhesive. Used selected ion scanning and standard curves of internal standard method for the quantitative analysis for benzene,toluene and xylene in adhesive content. Experimental results showed that this method was simple,rapid,sensitive and reproducible. Recoveries of the method ranged 92.3% to 100.4%,the relative standard deviations of three measures were in the range of 1.45%~4.58%.
