Vergleich von Röntgen- und optischer Emissionsspektralanalyse mit der Glimmlampe bei Anwendung auf AgCu-Binärlegierungen

Abstract

For the binary eutectic system AgCu, calibration curves are established over a large concentration range (0.3–99.7%). These calibration curves are bent in X-ray spectrochemical analysis as well as in optical emission spectral analysis with a glow discharge lamp as a result of matrix effects. Linearization is achieved by the “method of binary ratios.” By making use of this simple calibration method, it is possible to obtain results with high precision and accuracy: the relative S. D. depends on concentration and is approximately 0.05(1− c). Both methods of spectrochemical analysis are therefore suitable (at least for binary systems) for the determination of major and minor constituents.
