Abstract:Solid phase microextraction(SPME) can be effectively used to extract volatile and semivoltaile organic compounds from different environmental matrix. In this paper, we utilize headspace-SPME technique combined with capillary gas chromatography (CGC) and a laboratory modified flame photometric detector using quartz surfaceinduced luminescence (QSIL-FPD) for analyzing butyltin compounds in sediments. The detection limits of mono-,di-, and tri-butyltin compounds, based on the signal equal to 3 times the baseline noise are 16.9 ng/g, 1.58 ng/g adn 0.17 ng/g, respectively.
Keywords:Solid phase microextraction, capillary gas chromatography,quartz surface-induced luminescence,flame photometric detector, butyltins
