摘要
目的建立顶空气相色谱-质谱检测食品包装材料中10种残留有机溶剂的分析方法。方法采用GC-MS选择离子监测(SIM)模式进行定量分析。结果10种溶剂在0.001~0.1 mg/m2浓度范围线性关系良好,相关系数在0.9999~1.0000,对最低浓度点进行了重现性实验, RSD 均小于10%,回收率79.0%~106.2%,精密度1.08％~8.02％。结论此方法快速、准确可以满足国内外对食品包装材料中10种残留有机溶剂的同时检测。
Objective To establish a method for the determination of 10 residual solvents released from the food packaging material by the headspace gas chromatography-mass spectrometry. Methods The method was established by gas chromatography mass spectrum with selected ion monitor (GC-MS/SIM). Results The linear range of 10 residual solvents were 0.001~0.1 mg/m2 with correlative coefficient of0.9999~1.00000. The coefficient of variation was<10% on the lowest concentration. The average recoveries were 79.0%~106.2% with the relative standard deviations (RSD) of 1.08%~8.02%. Conclusion This analysis method is rapid and accurate, and it can be used for the simultaneous determination of 10 residual solvents released from the food packaging material.
