Abstract
La présente invention a pour objet un appareil de détection de traces de vapeurs et de gaz dans de l'air ou une autre atmosphère. Elle est caractérisée en ce que l'appareil comprend un carter 10 délimitant un passage d'écoulement de gaz dans lequel est placée une source de rayonnement ionisant, une zone de recombinaison 26, 27, 28 formée dans une première partie du passage, une zone de glissement 40 formée dans une seconde partie du passage et comportant une électrode collectrice 30, des moyens 62, 63, 64 d'établissement de potentiel de glissement, une valve 41, 48 permettant seulement à des ions d'une mobilité prédéterminée d'arriver à l'électrode collectrice et un moyen 51 pour mesurer le nombre d'ions atteignant cette électrode. Elle se rapporte au contrôle de la pollution.
