Automated gel permeation chromatographic clean-up of human adipose tissue for multiresidue analysis of organochlorine compounds.

Human adipose tissue samples have been analysed for organochlorine pesticides and polychlorinated biphenyls (PCBs). Following a micro liquid-solid extraction, clean-up is performed by automated gel permeation chromatography. The GPC separation provides clean extracts, allowing subsequential analysis by capillary gas chromatography-electron capture detection without additional clean-up.
