Abstract

Objective Establish the method for the determination of benzene,toluene,ethyl benzene,xylene,benzene,xylene and styrene(7 analytes) in adhesives by gas chromatography with headspace-direct injection.Method The column in gas chromatography,the heating temperature of headspace and headspace extraction time were discussed.Result 7 analytes detection limits are less than 5 mg/kg,7 kinds of components in a capillary column can be separated well,the recovery rate is in the range of 81%～94%,RSD is 5% ～ 10%.The method is fast and simple to operate.Conclusion This method is able to meet for determination and analysis requirements of the adhesives of benzene series compounds.
