A novel sample preparation technique so called "Vial sorptive extraction (VSE)" was developed. The VSE method uses a vial whose internal wall is coated with polydimethylsiloxane (PDMS). In this study, the optimization of the shape of vial sorptive extraction device and the film thickness of the PDMS were performed. In addition, other extraction mediums such as phenyl binding PDMS, polymethacrylate and styrene divinylbenzene copolymer were investigated. The method was applied to the determination of trace amount of bisphenol A in water sample as environmental application.

本文提出了一种新的样品前处理技术--“小瓶吸附萃取法”。VSE方法使用内壁涂有聚二甲基硅氧烷（PDMS）的小瓶。在本研究中，对吸附式萃取装置的形状和PDMS膜的厚度进行了优化。此外，还考察了其他萃取介质，如苯基结合的PDMS、聚甲基丙烯酸酯和苯乙烯-二乙烯苯共聚物。该方法已用于环境水样中痕量双酚A的测定。
