Zusammenfassung

Die Nachweisgrenzen von Ag, As, Au, Bi, Cd, Cr, Fe, Mn, Ni, P, Pb, Sb, Se und Te in Anwesenheit von 50 μg Kupfer wurden mit Hilfe der Zeeman Graphitofen-Atomabsorptionsspektrometrie (Zeeman/GAAS) unter Anwendung der Ensemblesummierung bestimmt. Diese ermöglicht die Bearbeitung der Atomabsorptions-Signale von Massen in der Nähe der entsprechenden Nachweisgrenzen.

Summary

The detection limits of Ag, As, Au, Bi, Cd, Cr, Fe, Mn, Ni, P, Pb, Sb, Se and Te in the presence of 50 μg of copper are determined by Zeeman graphite furnace atomic absorption spectrometry (Zeeman/GFAAS) using the method of ensemble summation. Processing of atomic absorption signals of masses close to the detection limits is illustrated.
