Zusammenfassung
Die Funkenmassenspektrometrie (SSMS) ermöglicht die Bestimmung von Haupt-, Neben- und Spurenelementen in Festkörpern. Die verschiedenen Möglichkeiten der quantitativen Multielementanalyse werden beschrieben und verglichen. Mit dem Peaksprungverfahren und der Isotopenverdünnungsmethode erreicht man eine Genauigkeit von ungefähr 2 %. Die Anwendbarkeit der Funkenmassenspektrometrie in der Geo- und Kosmochemie wird an Hand von Beispielen gezeigt.
Abstract
Spark source mass spectrometry (SSMS) allows the determination of major, minor and trace elements in solid samples. The different techniques for quantitative multielement analyses are described and compared. A precision of about 2% is achieved by peak switching and isotope dilution. The applicability of SSMS in geo- and cosmochemistry is demonstrated by examples.
Résumé
La spectrométrie de masse à étincelles (SSMS) permet de déterminer les éléments majeurs, mineurs et les traces dans des échantillons solides. Les différentes techniques pour l'analyse quantitative des éléments sont décrites et comparées. Par balayage séquentiel et dilution isotopique, une précision d'environ 2 % est atteinte. L'application de la «SSMS» en géo- et cosmochimie est démontrée à partir d'exemples.
