Simultaneous Determination on Migration Amounts of 9 Kinds of Benzeneseries in Food Contact Materials and Products by Purge-and-trap/Gas Chromatography-Mass Spectrometry
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(,r,2,) 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.
