Abstract
A liquid chromatography system with a potentiometric microelectrode at the exit end of an open-tubular LC column of 3.5μm i. d. nearly shows the theoretically [2, 10] predicted performance of 980 000 theoretical plates for non-retained components at a retention time of a few minutes. Possibilities of controlling the position of the microelectrode tip are given. A distance of one column i. d. between detector and column leads to a loss in column performance of about 15%.
