A gas chromatography-mass spectrometry (GC-MS) method has been established for the determination of benzene and toluene in laminated food packaging bags. The samples are dissolved by ethyl acetate, After the extraction in the ultrasound device using GC-MS detection. Between 0~100.0mg/L, the linearly dependent coefficient of the curve is 0.999, the recovery is 90.3%~94.5%. The limits of detection is 1.4mg /kg, RSD is 1.0%.The paper shows that the analytical method by GC-MS has many advantages, such as sensitive, effective, stable and etc. The test result is satisfied.
