Summary

A simple and quick method for the microdetermination of carbon and hydrogen is described. The substance is oxidized by copper oxide and the combustion gases are transported by nitrogen. Nitrogen oxides are removed by reduced copper. Sulphur-containing compounds are combusted over manganese oxide-silver oxide catalyst. With one filling more than 300 analyses can be performed.

Zusammenfassung

Eine einfache und schnelle Methode zur Mikrobestimmung von Kohlenstoff und Wasserstoff wurde beschrieben. Die Substanz wird mit Kupferoxid oxydiert, als Transportgas dient Stickstoff. Stickstoffoxide werden mit reduziertem Kupfer entfernt. Schwefelhältige Verbindungen werden über einem Manganoxid-Silberoxid-Katalysator verbrannt. Eine Rohrfüllung reicht für mehr als 300 Analysen.

Résumé

On décrit une méthode simple et rapide pour le microdosage du carbone et de l'hydrogène. On oxyde la substance par l'oxyde de cuivre et l'on utilise l'azote comme gaz vecteur pour les gaz de combustion. On élimine les oxydes de l'azote par le cuivre réduit. On brûle les composés contenant du soufre sur catalyseur manganèse-oxyde d'argent. Un seul remplissage permet de réaliser plus de 300 analyses.
