The online coupling of zone electrophoretic and isotachophoretic sample treatment with column liq. chromatog. (LC) is described. The electrophoretic sample treatment methods are carried out in free soln. Zone electrophoretic sample treatment (ZEST) of 20 mm3 of sample takes about 20 min. The applicability of ZEST to environmental analyses is demonstrated with the detn. of bentazone in water from the river Rhine. Preliminary results are presented for the online coupling of isotachophoresis (ITP) with LC, using a single switching valve. With ITP 30 mm3 sample vols., which can be concd. to an injection vol. of 5 mm3, can be treated within 17 min
