Zusammenfassung

Die Isotopenverteilung von stabilen Isotopen in sechs angereicherten Metallen (Calcium, Kupfer, Barium, Rubidium, Strontium und Thallium) wurde mit der Felddesorptions-Massenspektrometrie quantitativ bestimmt. Drei verschiedene Typen von Massenspektrometern in drei verschiedenen Laboratorien wurden für diese Untersuchungen benutzt und es ergab sich eine erste Wertung für die Reproduzierbarkeit dieses Verfahrens bei der Spurenbestimmung von Metallen. Die Standardabweichungen für das jeweils häufigste Isotop der untersuchten Metalle lag zwischen +-0.1 und +-0.5 %. Die quantitativen Resultate der drei massenspektrometrischen Arbeitsgruppen stimmten gut überein und lagen alle innerhalb dieses Bereichs der Standardabweichung. Um die Richtigkeit dieser Quantifizierung abzustützen, wurden die Proben der angereicherten Metalle ebenfalls mit der Thermionisations-Massenspektrometrie gemessen. Dieses zweite, unabhängige Verfahren bestätigt eindeutig die Ergebnisse der Felddesorptions-Massenspektrometrie.

Summary

The isotopic distribution of stable isotopes in six enriched metals (calcium, copper, barium, rubidium, strontium and thallium) has been determined by field desorption mass spectrometry. A first evaluation of the interlaboratory reproducibility of the application of this method for trace determination of metals was made using three different types of mass spectrometers in three different laboratories. The standard deviations for the most abundant isotopes of the metals investigated are between +-0.1 and +-0.5%. Within these standard deviations, the values obtained by the three mass spectrometry groups are the same. To support the accuracy of our quantification, thermal ionization mass spectrometry has been employed and confirms the results of the field desorption method.
