Abstract

L'invention concerne un procédé de mesure de traces de gaz et l'appareil associé. L'appareil comprend un pulvérisateur 2 comportant des moyens 1, 3 et 4 d'introduction d'un gaz et d'un liquide de séparation, une chambre de séparation 7 et 8 et une chaîne de mesure électrochimique raccordée par un conducteur 9 pour liquide à la chambre de séparation, la chaîne de mesure possédant une électrode 10 sensible aux ions dotée d'un disque capteur 11 et une électrode de référence 13 dotée d'un diaphragme 13a, le disque étant placé de manière qu'il se forme une colonne de liquide d'absorption qui mouille toute sa surface et reste en contact avec le diaphragme. L'appareil de l'invention est d'un fonctionnement fiable et rapide. Il consomme de faibles quantités de liquide d'absorption. L'entretien et la vérification de l'appareil peuvent n'être effectués que toutes les 3 ou 4 semaines.
