Objective To develop a gas chromatography/mass spectrometry method for determination of organic residuals in food contact materials. Methods The organic residuals in food contact materials were determined by thermal desorption gas chromatography using mass spectrometry detector. Theorganic residuals were characterized according to retention time and was quantitatively determined byexternal standard method. Results Recoveries of typical organic residuals were between 92.7%~112.5% with RSD less than 3.2%, R2>0.9890, and limit of detection ranged from 0.06~0.11 mg/L. Conclusion This method is sensitive, accurate and precise and it is suitable for the detection oforganic residuals in many kinds of materials.
