Gold and fold alloys. X-ray fluorescent method for determination of gold content

This technical specification outlines the procedure for determining the gold content in precious metals and gold alloys using X-ray fluorescence (XRF) analysis. The method provides a non-destructive approach to measure the elemental composition, ensuring accuracy and reliability for quality control purposes in the industry. It covers the calibration of equipment, preparation of sample specimens, and the interpretation of spectral data obtained during the analysis process. The protocol addresses various forms of gold products, including bars, coins, and jewelry, offering a standardized framework for laboratories to follow. By adhering to these guidelines, testing facilities can achieve consistent results that facilitate trade and compliance with regulatory requirements. The procedure emphasizes the importance of proper instrument settings and environmental controls to minimize measurement errors. This approach is widely recognized for its efficiency in assessing the purity of gold materials without altering the physical state of the sample.
