气质联用测定酒中邻苯二甲酸酯类残余物方法的改进

Improvement of Determination Method of Phthalates Residue in Wine by GC/MS

本文改进了酒中邻苯二甲酸酯类中邻苯二甲酸二异丁酯、邻苯二甲酸二丁酯、邻苯二甲酸(2-乙基)己酯检测方法。采用正己烷提取、浓缩后用气相色谱-质谱联用仪进行测定。采用特征离子扫描模式定性,以外标法定量。

This paper improved the detection method of isobutyl phthalate, dibutyl phthalate, phthalic acid （2-ethylhexyl） of phthalates in wine, used hexane extraction and GC/MS spectrometer after concentration for measurement, and applied characteristics ion-scan mode for qualitative analysis and the external reference method for quantitative analysis.
