为评估食品接触材料及制品中苯系物的迁移风险,建立了同时测定食品接触材料及制品中9种苯系物在4%乙酸、10%乙醇和橄榄油中迁移量的吹扫捕集/气相色谱-质谱联用法(P,&,T/GC-MS)。采用HP-INNOWax毛细管色谱柱对迁移实验后的9种苯系物进行分离,选择离子监测(SIM)模式进行检测。结果表明,9种苯系物的分离效果良好,在0.50 ~ 5.0 μg/kg或0.50 ~ 5.0 μg/L范围内线性关系良好,相关系数(,r,2,)均不小于0.995,方法检出限为0.15 μg/kg,方法定量下限为0.50 μg/kg,加标回收率为78.5% ~ 107%,相对标准偏差(,n ,= 6)为1.1% ~ 9.2%。该方法具有较高的准确度和较好的重现性,可用于食品接触材料及其制品中9种苯系物迁移量的测定。
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.
