Abstract

Dans une pile à oxygène dont la pression partielle d'oxygène inconnue est dérivée en mesurant la f.é.m. d'une pile à concentration, la génération de la pression partielle d'oxygène connue est effectuée en employant une substance qui réagit avec l'oxygène en formant des composés qui sont facilement éliminés du lieu de la réaction. On supprime, ainsi, le problème de la polarisation de la pile dont la vie utile est prolongée et le signal reste extremement précis à long terme.In an oxygen cell from which the unknown partial pressure of oxygen is derived by measuring the emf. of a concentration cell, the generation of the known partial pressure of oxygen is carried out using a substance which reacts with oxygen to form compounds which are easily eliminated from the place of the reaction. This eliminates the problem of battery polarization, the useful life of which is extended and the signal remains extremely precise in the long term.
