Abstract

a. Dispositif pour supprimer la sensibilité transversale à la vapeur d'eau dans un analyseur de gaz par rayonnement infrarouge non dispersif. b. L'analyseur se compose d'une source 1 de rayonnement infrarouge, d'une cuve 3 de mesure, d'une cuve-filtre 4 et d'un récepteur sélectif de rayonnement ayant la forme d'une chambre 5 emplie de gaz. La cuve-filtre 4 contient de l'hexafluorure de soufre à la place de la vapeur d'eau qui est utilisée habituellement. c. Analyse des gaz.
