| Abstract: | A sol-gel material was successfully applied to preparing a novel coating as a precursor for solid phase microextraction(SPME).A homemade fiber based on solgel polydimethylsiloxane(PDMS) SPME coating was prepared by hydrolysis of alkoxide precursors and subsequent polycondensation with OH-TSO.The characteristics of the new coating were investigated by the analysis of pesticide standard solution mixture in conjunction with gas chromatograph(GC).The proposed fiber presented a wide linear range for target analy... |
