Gold and fold alloys. Determination of gold content by X-ray fluorescent method

This technical specification outlines the procedure for determining gold content in gold and gold alloys using X-ray fluorescence analysis. It establishes a standardized methodology that ensures accuracy and consistency in measuring the purity of precious metals across various industrial applications. The approach relies on non-destructive analytical techniques, allowing for the precise identification of elemental composition without damaging the tested specimen. By defining specific operational parameters and calibration requirements, the document provides a reliable framework for laboratories and manufacturing facilities. The method is designed to handle a wide range of sample types and alloy compositions, facilitating quality control processes in jewelry production and bullion trading. Adherence to these guidelines enables stakeholders to obtain comparable results regardless of the testing location, thereby supporting international trade and regulatory compliance in the precious metals sector. The procedure emphasizes the importance of proper sample preparation, instrument settings, and data interpretation to maintain high analytical standards.
