Abstract

L'invention concerne les cellules d'électrolyse destinées à l'analyse électrochimique d'échantillons en solution. Elle se rapporte à un appareil qui comprend une cellule d'électrolyse ayant une électrode 34 dont surface interne formé plusieurs électrodes dont au moins deux segments actifs d'analyse, une électrode auxiliaire et une électrode de référence. Les potentiels électriques sont mesurés pour plusieurs substances présentes dans l'échantillon, si bien que l'appareil peut donner directement, par soustraction, la valeur correspondant à une substance choisie. Application à l'analyse automatique du sang et du sérum.
