Abstract

Analytical Chemistry Other Chemical Sciences Chemical Engineering emission analysis gold alloys
The accuracy of emission determinations of gold, silver and copper in ordered Au/Ag/Cu alloys is compared with similar determinations when these alloys are disordered. The relative slope factors, KCu and KAg, depend on the concentration of copper present. The accuracy obtained in the analysis of the disordered alloys cannot be achieved for the ordered ones unless the standards used closely match the samples in composition. The ordered phase responsible for the effect is CuAu.
