SPME Fiber Coating

Researchers from Fudan University (Shanghai, China) and Nanjing University (Nanjing, China) have proposed the use of polythiophene as a coating for a solid-phase microextraction (SPME) device. The researchers used an electrodeposition process to coat a stainless steel wire with the compound. The coated wire was then used to extract organochlorine pesticides from water samples. The extracted analytes were analyzed by gas chromatography. The new coating was found to work as well as carbowax?divinylbenzene fibers currently in use.
