Abstract:In this study, a needle trap extraction device with a molecularly imprinted polymer coated on Dupont fibers was developed for extraction. A number of heat-resistant Dupont fibers were longitudinally filled into a glass capillary, followed by coating with a molecularly imprinted polymer as an extraction medium and were used to extract volatile organic compounds from environment. Subsequently, the extracted analytes were analyzed by gas chromatography. The linear detection range, recovery, limit of detection (LO… Show more
