Popis: A method for trace analysis incorporating solid phase extraction (extraction and clean-up) with supercritical fluid chromatography (SFC) for analytes in fats and oils has been developed. Direct coupling (on-line) of supercritical fluid solid phase extraction with supercritical fluid chromatography (SESPE/SFC) allows analysis of solutes in fats and oils for which on-line SFE/SFC is unsuitable. The main feature of SFSPE/SFC is that extraction and clean-up are accomplished in one step using unmodified supercritical carbon dioxide. Extraction/clean-up is monitored by a photodiode array detector which allows fractionation. The operational set-up and potential usefulness of the SFSPE/SFC system and applications for pesticide analysis of lipid sample matrices are described.
