| 摘 要： | 建立了顶空固相微萃取-气相色谱串联质谱检测葡萄酒中主要的痕量木塞污染物——2,4,6-三氯苯甲醚（TCA）的方法。通过优化萃取时间、温度、盐浓度、pH值等固相微萃取处理条件,采用2,4,6-三氯甲苯（TCT）为内标进行定量,气相色谱离子阱质谱法测定。选取TCA母离子和子离子分别为m/z210和m/z195,TCT的母离子和子离子为m/z195和m/z159。方法的定量下限（LOQ）为2.0 ng/L,回收率为71%-98%。该法操作简单、快速,适用于葡萄酒中痕量TCA残留的快速检测。

| Abstract: | A method for determination of trace level of 2,4,6-trichloroanisole(TCA) in wine has been presented by using headspace solid-phase microextraction-gas chromatography coupled to tandem mass spectrometry(SPME-GC-MS/MS).The extraction parameters such as time,temperature,salt concentration,and sample volume were optimized.The analysis was performed by GC-MS/MS using 2,4,6-trichlorotoluene(TCT) as an internal standard.The m/z 210 and 195 were selected as the parent ions and m/z 195 and 159 as the daughter ion fo... |
