Summary
The advantageous features of the incorporation of ion-sensitive electrodes (ISEs) in flow systems are outlined with particular emphasis on the improved performance obtained with the flow injection approach. Moreover, the controlled way of sample dispersion is shown to offer “unique possibilities”, i.e. applications which cannot be done in batch or continuous flow measurements. Examples for this are the kinetic discrimination for selectivity enhancement, the lowering of detection limits, indirect determinations without titration, series differential detection and a novel means of calibration and continuous monitoring.
