| Abstract: |
| In order to evaluate the migration risk of benzeneseries from food contact materials and products，a purge-and-trap/gas chromatography－mass spectrometry（P&T/GC－MS） was developed for the simultaneous determination of nine benzene compounds in food contact materials and products．Food simulants included 4% acetic acid，10% ethanol and olive oil. 9 kinds of benzeneseries were separated on an HP－INNOWax capillary column，and detected by MS in selected ion monitoring（SIM） mode．Results showed that there were good linear relationships for the analytes in the range of 0.50－5.0 μg/kg or 0.50－5.0 μg/L，with their correlation coefficients（r2） not less than 0.995．The limits of detection and limits of quantitation of the method were 0.15 μg/kg and 0.50 μg/kg，respectively．The recoveries ranged from 78.5% to 107%，with the relative standard deviations（n = 6） of 1.1%－9.2%．With high accuracy and good reproducibility，the established method could be used to determine the migration of nine benzeneseries in food contact materials and their products. |
