ABSTRACT:
A method and an apparatus for instantaneously determining ions in a carrier solution by means of leading it into a very thin continuous layer over the sensitive surface of an ion-selective electrode in a measuring cell and, from said measuring cell, on to a reservoir having a reference electrode so that the potential difference between the electrodes in the measuring cell can be continuously registered. The apparatus consists of a circuit having an inlet conduit, a pump, a sample addition apparatus, a loop, the measuring cell and a conduit via the pump to an outlet. The liquid level in the measuring cell is held constant, the ion-selective electrode being arranged above the liquid level and the reference electrode being immersed in the solution.
