    Abstract

    A series of chromatographic processes has been integrated into an automated sequential procedure that has been specifically developed for uninterrupted purification and fractionation of multiclass organic chemical residues from environmental samples. The effectiveness and general applicability of this sequential cleanup and fractionation procedure were demonstrated by the recovery of 39 chemicals representing a broad range of residue classes from a fortified fish sample. A chromatographic controller under construction is designed to carry out the numerous sample and solvent manipulations in an automated and continuous procedure. Alkali metal hydroxide treated silica gel effectively separated phenols and acids from neutral compounds.
