Abstract

A method of determining the concentration of a given ion in an aqueous sample with the aid of an ion-selective electrode (4) and a reference electrode (5) placed in a measuring cell (3) by delivering the sample to the cell in an air-segmented form; effecting measurement with the electrodes; flushing the sample from the measuring cell subsequent to said measuring operation and replacing said sample with a conditioning solution (7) of known ion concentration; and immediately standardizing the electrode system, by measuring with the electrodes in the conditioning solution. A measuring arrangement including a measuring cell (3) with an ion-selective electrode (4) and a reference electrode (5) and constructed so that air bubbles in the sample delivered thereto will not come into contact with the active surfaces of the electrodes; intermittently working pumps (1, 2) for delivering air segmented sample solution and a conditioning solution (7) to the cell (3) and for evacuating the cell; and a sample storage loop (11) disposed between an inlet (19) to the cell and a tube (14) delivering the conditioning solution (7).
