    Description

    Extensive preparation of samples before chromatographic analysis is usually the most time-consuming process in the determination of many organic compounds in environmental matrices. In the past, removal of some organic from aqueous solution was commonly done by liquid/liquid extraction. However, the introduction of stable, covalently bonded reversed-phase sorbents now allows efficient removal of hydrophobic compounds from aqueous solution by adsorption anachromatographic support. Solid-phase extraction is not anew technique. However, the procedure is more convenient today because of the commercial availability of ancillary equipment and prepackaged disposable adsorption cartridges ins variety of sorbents (1, 2).
