Abstract

a. L'invention concerne la mesure de la quantité d'hydrogène existant dans un métal, sous forme de soudure en particulier, et un appareil pour son exécution. b. Dans un système où passe continuellement un gaz véhiculeur, on place un collecteur muni éventuellement d'un four de chauffage, contenant une éprouvette métallique qui dégage l'hydrogene que l'on envoie à un analyseur, les résultats des analyses étant traités dans un calculateur approprié. c. La limite inférieure de détection de l'hydrogène est extrêmement basse bien que la précision soit améliorée.
