Assessment Of Non-Destructive Testing Methods for Gold 916: Using Energy Dispersive X-Ray Fluorescence
The demand for non-destructive methods to determine the purity of gold 916 has increased significantly due to gold's status as a secure investment. In Malaysia's gold industry, ensuring purity remains a major challenge, as fake gold jewelry containing adulterated gold items, such as gold 916 with significantly lower gold content which is below 91.6 percent, porosity, and undesirable impurities, has become prevalent. In this research project, a methodology is proposed to use one of common method for non-destructive which is Energy Dispersive X-Ray fluorescence (EDXRF) as this method will not destroy the sample during the process to test it. As a result, this research project presented a non-destructive testing method, EDXRF in order to test the authenticity for gold 916 with various compositions.
