Summary
Nitrogen can be determined with high accuracy in samples, including compounds which are difficult to burn, by using high temperature. Mixing with copper oxide is thus avoided.
Zusammenfassung
Substanzen auch schwerverbrennlicher Art können mit großer Genauigkeit bei hoher Temperatur ohne Mischen mit Kupferoxyd verbrannt werden.
Résumé
On peut doser l'azote dans des substances qui sont difficiles à brûler avec une grande exactitude en utilisant une température élevée. On évite ainsi le mélange avec l'oxyde de cuivre.
