In this paper,a method for the separation and determination of organic solvents such as toluene,isopropyl alcohol,butanone,ethyl acetate,et al in packaging materials is put forward through investigating the time and temptation of equilibrium of headspace sampling and chromatographic condition.This headspace sampling gas chromatography method can be used to detect 12 kinds of solvents simultaneously,and the recoveries of all solvents can range from 92.0%-98.2%.What＇s more,this simple and quick method has a high sensitivity.
