    Description / Table of Contents: Summary The oxygen determination in low-oxygen aluminium is performed by helium-3 activation analysis. The influence of other impurities in the matrix and the method of their elimination without any chemical separation is discussed. Major interferences were eliminated by etching the samples after irradiation. Oxygen contents of 0.7±0.1 ppm were found.
    Notes: Zusammenfassung Zur Sauerstoffbestimmung in sauerstoffarmen Aluminiumproben wird die Aktivierungsanalyse mit3He empfohlen. Der Einfluß von anderen Verunreinigungen und dessen Beseitigung ohne chemische Trennung werden diskutiert. Die hauptsächlichen Störungen werden durch Ätzen der Probe nach der Bestrahlung verhindert. Sauerstoffgehalte von 0,7±0,1 ppm wurden bestimmt.
