| 摘 要： | 采用固相微萃取-气相色谱法测定葡萄酒及软木塞中的TCA含量,样品试液经固相微萃取装置萃取、富集后,直接无分流进样,经毛细管柱DB-5分离后,用ECD检测器检测。结果表明,该方法检出限为0.1 ng/L,回收率在90%～106%之间,相对标准偏差(n=5)小于5%。

| Abstract: | 2,4,6-trichloroanisol(TCA) content in grape wine and cork stopper was determined by SPME-GC.TCA in the sample solution was ex-tracted and concentrated to SPME fibre.By splitless injection and capillarity column DB-5 separation,TCA was then determined by ECD.The re-sults showed that the detection limit was 0.1 ng/L and the recovery was between 90 % to 106 % and RSD(n=5) was less than 5 %. |
