气相色谱-质谱法测定塑料玩具中的多环芳烃

Determination of Polycyclic Aromatic Hydrocarbons in Plastic Toys by Gas Chromatography-Mass Spectrometry

文章先分析了多环芳烃和塑料制品,随后介绍了试验部分,包括试验仪器和试剂、气相色谱-质谱条件、试验方法,最后介绍了结果和讨论,包括超声提取时间选择、方法检出限与线性回归方程、方法回收率、样品分析。

The article first analyzes polycyclic aromatic hydrocarbons and plastic products,and then introduces the test part,including test instruments and reagents,gas chromatography-mass spectrometry conditions,test methods and finally introduces the results and discussions,including ultrasonic extraction time selection,method detection limit and linear regression equation,method recovery,sample analysis.
