Lipophilic organic substances, whether man-made, mobilized by human activities, or of recent natural origin, are usually dissolved in sea water at such minute concentrations that the chemical characterization and quantitative determination of single compounds are possible only after a sufficient quantity has been collected by concentration from relatively large (of the order of 100-1000 litres) volumes. Essentially two techniques have found widespread application in marine organic chemistry and pollution research, i.e., extraction, either batchwise or continuous, with a suitable water-immiscible solvent (Duinker and Hillebrand, 1983, and references cited therein) or sorption onto solids (Duinker and Hillebrand 1983, loco cit.; Ehrhardt, 1983). Described below is a new apparatus and technique for purifying sorbant material from substances interfering with ultra-trace ana.....
