Abstract

Procédé et dispositif pour la détermination de la teneur totale en azote dans des systèmes aqueux. Ce procédé consiste à faire passer un courant de gaz inerte, ne contenant sensiblement pas d'azote et d'anhydride carbonique, à travers une tube de réaction, qui est garni avec un catalyseur de décomposition et maintenu à une température de 700 à 1200 degrés C, un condenseur 8 et un tube 9 absorption d'humidité, dans cet ordre, à injecter un échantillon expérimental aqueux à analyser dans le tube de réaction et à envoyer les produits gazeux sortant du tube d'absorption d'humidite à un spectromètre de masse pour déterminer la teneur en azote. La présente invention est particulièrement utile pour déterminer la teneur en azote totale dans des composés azotés contenus dans des systèmes aqueux, de manière rapide et précise, et avec une grande sensibilité
