Abstract

APPAREIL DE MESURE ELECTROCHIMIQUE PAR DIFFUSION POUR DETERMINER LA CONCENTRATION D'UN GAZ DANS UN LIQUIDE. L'ELECTRODE DE REFERENCE 10, EN ARGENT, EST FIXEE A L'EXTERIEUR D'UN CORPS 1 NON CONDUCTEUR ET EST BAIGNEE PAR L'ELECTROLYTE 15, ACIDE, SE TROUVANT DANS L'ESPACE 9 ENTRE LE CORPS 1 ET UNE DOUILLE 2. L'ELECTRODE DE MESURE 5 ENFONCEE A FORCE DANS LE CORPS 1 EST EN CARBONE ET COMMUNIQUE AVEC LE LIQUIDE PAR L'INTERMEDIAIRE D'UN ELEMENT DIFFUSEUR 14 EN POLYESTER ET D'UNE MEMBRANE, NON CONDUCTRICE, EN TISSU MAILLE PERMEABLE AU GAZ A DOSER. LES DEUX ELECTRODES SONT RELIEES A TRAVERS UN AMPEREMETRE QUI MESURE L'INTENSITE DU COURANT QUAND LE BAS DE L'APPAREIL EST PLONGE DANS LE LIQUIDE. DETERMINATION DE LA CONCENTRATION EN IONS SULFITE OU NITRITE DE PRODUITS ALIMENTAIRES (VIN).
