Summary

A critical study has been made of the application of the rapidVečeřa cobalto-cobaltic oxide method, the rapidKorshun-Klimova straight empty tube method and the rapidBelcher-Ingram empty tube method for the microdetermination of carbon and hydrogen in steroids. Simple but effective modifications have been introduced so that any of the three methods can be applied to obtain accurate results; the maximum error is ± 0.3% for a representative variety of structures.

Zusammenfassung

Eine kritische Untersuchung der Anwendbarkeit der drei Methoden vonVečeřa mit Co3O4, vonKorshun undKlimova mit dem senkrechten leeren Rohr sowie vonBelcher undIngram mit dem leeren Rohr für die CH-Mikrobestimmung in Steroiden wurde ausgeführt. Einfache, aber wirksame Abänderungen wurden angegeben, so daß alle drei Verfahren zu genauen Ergebnissen führen. Der maximale Fehler beträgt ± 0,3% bei einer großen Zahl verschieden strukturierter Substanzen.
