Zusammenfassung

Um auch thermolabile Substanzen mit der Ringofenmethode untersuchen zu können, wird an Stelle der sonst üblichen „Temperaturbarriere“ eine „Adsorptionsbarriere“ vorgeschlagen. Mit Hilfe des Ringofens wird eine scharf ausgebildete ringförmige Zone eines Adsorptionsmittels auf Filterpapier hergestellt. Die zu konzentrierenden Substanzen werden mit einem Lösungsmittel — ohne Verwendung des Ringofens selbst — in diese Zone gewaschen.

Summary

To permit also the investigation of thermo-labile substances by the ring-furnace method, it has been suggested that the usual “temperature barrier” be substituted by an “adsorption barrier”. A sharply developed ring-shaped zone of an adsorption agent is produced on filter paper with the aid of the ring furnace. The substances to be concentrated are washed into this zone by means of a solvent without employing the ring furnace itself.
