(FR) CELLULE ELECTROCHIMIQUE
Abstract:
(EN) The present invention relates to electrochemical cells including a first working electrode 32, a first counter electrode 34, a second working electrode 36, and a second counter electrode 38, wherein the electrodes are spaced such that reaction products from the first counter electrode 34 arrive at the first working electrode 32, and reaction products from the first and second counter electrodes 34, 38 do not reach the second working electrode 36. Also provided is a method of using such electrochemical cells for determining the concentration of a reduced or oxidized form of a redox species with greater accuracy than can be obtained using an electrochemical cell having a single working and counter electrode.
(FR) La présente invention comprend des cellules électrochimiques comprenant une première électrode active (32), une première contre-électrode (34), une deuxième électrode active (36) et une deuxième contre-électrode (38), lesdites électrodes étant espacées de manière à ce que les produits de réaction provenant de la première contre-électrode (34) arrivent sur la première électrode active (32) et que les produits de réaction des première et deuxième contre-électrodes (34, 38) n'atteignent par la deuxième contre-électrode (36). L'invention concerne aussi un procédé d'utilisation de ces cellules électrochimiques pour déterminer la concentration d'une forme réduite ou oxydée d'une espèce de redox avec une précision plus grande que celle pouvant être obtenue au moyen d'une cellule électrochimique possédant une électrode active et une contre-électrode uniques.
