The energy dispersive X-ray fluorescence spectrometer (EDXRF) technique is one of the most versatile and popular analytical methods for the elemental analysis of Precious metals and karat identification. All the noble metals can be analyzed in a short period of time with high accuracy, precision and reliability. The virtue of its simplicity, non-destructive, speed, affordability and reliability are clearly advantageous over traditional wet chemistry (fire assay for example) and other spectroscopic methods. Modern technological developments have also helped to include EDXRF into standard test methods for Jewelry application. This application note proves that EDX6000D is mature enough to establish clear qualitative and quantitative characterization of the gold value as well as Karat grade.
