Inter-laboratory note. Multi-element analysis of archaeological bronze objects using inductively coupled plasma atomic emission spectrometry: aspects of sample preparation and spectral line selection

Abstract

Inductively coupled plasma atomic emission spectrometry has been applied to the determination of trace and minor elements in archeological bronzes. Trace element spectral lines were selected on the basis of minimum interference from major element matrix components, i.e., Cu, Pb, Fe and Sn. Using Sc as the internal reference element provided a significant improvement in the relative standard deviation. Accuracy, evaluated using standard reference alloys of similar composition, was satisfactory.
