Abstract

L'invention concerne un procédé et un appareil de détermination instantanée d'ions dans une solution de support. La solution de support s'écoule sous forme d'une très mince couche continue sur la surface sensible d'une électrode sélective vis-à-vis d'ions dans une cellule de mesure, et vers un réservoir contenant une électrode de référence. La différence de potentiel entre les électrodes est enregistrée continuellement. Le niveau du liquide dans la cellule est maintenu constant, l'électrode sélective aux ions étant placée au-dessus du niveau et l'électrode de référence au-dessous. L'invention s'applique notamment à la détermination du potassium dans des extraits de sol ou dans le sérum sanguin.
