Title (EN) ELECTROCHEMICAL ASSEMBLY
(FR) MONTAGE ELECTROCHIMIQUE
Abstract:
(EN) An electrochemical assembly (30) for continuously monitoring the level of ammonia in a fermenting medium comprises a housing (14) incorporating a gas-permeable ion-impermeable outer membrane (21) which is capable of transmitting ammonia from the medium into the housing (14). A monitor electrode is located within housing (14) and incorporates a monovalent cation-sensitive-glass inner membrane (19) the latter being separated from outer membrane (21) by a thin aqueous film (20) of electrolyte solution which is pH buffered. A reference electrode (16) is provided within housing (14) and an electrical connection (17) is provided between the film (20) and the reference electrode (16).
(FR) Un montage électrochimique (30) pour surveiller en continu le taux d'ammoniaque dans un milieu de fermentation comporte un boîtier (14) renfermant une membrane extérieure (21) perméable aux gaz et imperméable aux ions, capable de transmettre l'ammoniaque du milieu au boîtier (14). Une électrode de surveillance est située à l'intérieur du boîtier (14) et comporte une membrane intérieure (19) en verre sensible aux cations monovalents, qui est séparée de la membrane extérieure (21) par un mince film aqueux (20) d'une solution électrolytique à pH tamponné. Une électrode de référence (16) est prévue dans le boîtier (14), alors qu'une connexion électrique (17) est prévue entre le film (20) et l'électrode de référence (16).
