Abstract

Cellule électro-analytique destinée à mesurer la concentration d'un composé électro-actif, tel que l'oxygène, dans un fluide gazeux ou liquide, tel qu'un mélange de gaz ou de l'eau, et comprenant une paire électrodes, en contact avec un électrolyte, et une membrane séparant l'électrolyte du fluide. La cellule possède une troisième électrode en contact avec l'électrolyte. La surface de la troisième électrode forme une limite d'une fente de diffusion. La troisième électrode peut être maintenue à une tension propre à protéger la surface de l'électrode de travail contre des courants et contributions électroniques parasites indésirables. De préférence, la tension de la troisieme électrode est sensiblement celle de l'électrode de travail. Cette cellule confère une précision de mesure élevée, un élargissement de la gamme de mesure vers des concentrations de gaz faibles, une sensibilité faible contre les chocs ou vibrations ainsi qu'une simplification de la réponse en régime transitoire.
