Gold and gold alloy reference materials for XRF analysis

Abstract

A method for the production of a series of certified gold reference materials is presented. These reference materials are intended for use in the analysis of the elemental composition of gold alloys using a non-destructive X-Ray Florescence (XRF) spectrometry method. The chemical composition of the reference materials covers the complete range of conventional coloured and white carat gold jewellery alloys. The XRF method based on this series of reference materials produces analytical results which are comparable with those obtained when using traditional chemical methods of analysis.
