MAS-GC/MS法检测乳制品饮料中的邻苯二甲酸酯类化合物

Determination of 16 Phthalates in Milk by Multi-function Impurity Adsorption SPE and Chromatography/Mass Spectrometry

文章以多重机制杂质吸附萃取净化法(MAS)快速样品前处理法和GC/MS结合,建立了针对乳制品饮料中16种邻苯二甲酸酯类化合物的快速检测方法。以纯牛奶、酸奶为实验对象,采用Cleanert MAS-PAE离心管进行前处理,通过气相色谱-质谱联用法(GC/MS)进行定性和定量检测。实验结果表明,该实验方法对所选的样品净化效果较好,实验操作快速简便,可大大提高工作效率。

To establish a quick and accurate method used for determination of 16 phthalates（PAEs） in milk by Multi-function Impurity Adsorption SPE and chromatography/mass spectrometry. Glass hardware Cleanert MAS-PAE cartridges without PAEs（MAS） were introduced to prepare milk sample. Qualitative and quantitative evaluation were perrormed by GC-MS. The method appeared to simple, accurate, and have good repeatability, purification effect.
