Research Abstract	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.
