[A novel solid phase coating of solid-phase microextraction prepared with sol-gel technology and its applications].
Abstract
In this paper, the recent development and applications of solid-phase microextraction (SPME) are summed up. A sol-gel method was applied for the preparation of solid phase coating in SPME. The exposed outer surface was coated with hydroxy-terminated poly (dimethylsiloxane). The characteristics of this solid phase were evaluated. The coating possesses higher thermal stability, and shorter extraction and desorption time. This solid phase appears to have strong affinity to both polar compounds and non-polar compounds. The scanning electron micrograph of the coated surface presents a porous structure. In the analyses of the environmental samples, ideal results were also obtained.
