Title (EN) ION SENSOR
(FR) CAPTEUR IONIQUE
Abstract:
(EN) An ion sensor which is prepared by covering a conductive base (1) with a redox function layer (5) composed of an electrolytic polymer membrane of a hydroxy or amino compound having a biphenyl skeleton, or a mixture thereof, etc., and covering the surface with an ion-selective layer (4). This ion sensor suffers less dissolution of the redox function layer (5) into the ion-selective layer (4), thus showing stable properties and having a long life.
(FR) Capteur ionique réalisé en recouvrant une base conductrice (1) d'une couche à fonction d'oxydoréduction (5) composée d'une membrane polymère électrolytique formée d'un composé hydroxy ou amino possédant un squelette biphényle, ou d'un mélange de ces composants, etc., et en recouvrant la surface d'une couche (4) sélective aux ions. Ce capteur ionique présente une dissolution moindre de la couche à fonction d'oxydoréduction (5) dans la couche (4) sélective aux ions, ce qui en améliore la stabilité et en prolonge la durée de vie.
