Abstract

Système d'électrodes pour mesure polarographique. Le perfectionnement du système réside en ce que la demi-cellule de référence usuelle est remplacée par une électrode solide telle qu'une électrode du deuxième type dont le potentiel est stabilisé à une concentration ionique constante d'une solution introduite dans la liqueur à tester.System of electrodes for polarographic measurement. The improvement of the system resides in that the usual reference half-cell is replaced by a solid electrode such as an electrode of the second type, the potential of which is stabilized at a constant ionic concentration of a solution introduced into the liquor to be tested.
