Abstract
The method uses an XRF instrument for identifying a specified element on a jewelry sample by illuminating its surface with excitation radiation and measuring first and second intensities of characteristic emission lines of a specified element and calculating the ratio between the intensities to establish a measured thickness and to determine based on a certain range criteria whether the sample can be considered to be plated jewelry.
