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.Electro-analytical cell intended to measure the concentration of an electro-active compound, such as oxygen, in a gaseous or liquid fluid, such as a mixture of gases or water, and comprising a pair of electrodes, in contact with an electrolyte, and a membrane separating the electrolyte from the fluid. The cell has a third electrode in contact with the electrolyte. The surface of the third electrode forms a boundary of a diffusion slit. The third electrode can be maintained at a voltage suitable for protecting the surface of the working electrode against unwanted parasitic currents and electronic contributions. Preferably, the voltage of the third electrode is substantially that of the working electrode. This cell provides high measurement precision, a widening of the measurement range towards low gas concentrations, low sensitivity against shocks or vibrations as well as a simplification of the response in transient conditions.
