抄録

An electric field application on ion exchange packing supports induced the release of sample solutes from the supports. When the electric field was applied temporary on the column, this phenomenon was observed as an increase in the pulsed concentration in the mobile phase. Namely a peak emerges on a chromatogram. The effect of the applied voltage on the ion exchange resin was examined by using a tiny mini-column. The sample solution was continuously passed through and the variations of effluent composition with and without application of electric field were analyzed. It was observed that amounts of increments of molar concentration of both benzoic acid and benzenesulfonic acid in mobile phase depended on the strength of the electric field. A theory of variation of distribution constant due to the electric field is proposed.
