顶空/气相色谱-质谱法分析方便面印刷包装材料中挥发性有机物OA北大核心CSCDCSTPCD
Analysis of Volatile Organic Compounds in Printing and Plastic Packaging Materials of Instant Noodles by Headspace Gas Chromatography-Mass Spectrometry
利用顶空/气相色谱-质谱(HS/GC-MS)联用法对袋装方便面印刷包装材料中7种挥发性有机物(异丙醇、乙酸乙酯、苯、乙酸丁酯、乙苯、间/对二甲苯、邻二甲苯)进行了检测分析.优化的实验参数为:平衡温度80℃,平衡时间40 min.本方法线性关系良好,7种挥发性有机物的相关系数均大于0.9991,检出限为0.004～0.007 mg/m2；回收率为93％～102％;相对标准偏差≤3.1％.结果表明:未印刷的塑料薄膜中包含异丙醇、乙酸乙酯、乙酸丁酯；印…查看全部>>
A headspace gas chromatography/mass spectrometric (HS/GC-MS) method was used to analyze seven volatile organic compounds (VOCs) including isopropyl alcohol, ethyl acetate, benzene, butyl acetate, ethyl benzene, m/p-Xylene, o-Xylene in printing and packaging materials of instant noodles. The important experiment parameters related to the HS/GC-MS method were optimized, equilibrium temperature of 80 °C and headspace equilibrium time of 40 min. In the experimen…查看全部>>
