In the gold trade, traditional hallmarking is recognized as proof of the quality and purity of a gold alloy. In this process, the specific precious metal content is stamped into the jewelry or gold bar using hallmarks. The analysis required in advance should be precise and non-destructive in order to prevent any reduction in the value of the item and to identify counterfeits. Fast measuring times are also important to ensure high throughput. The FISCHERSCOPE® X-RAY XDV®-SDD is ideally suited for alloy analyses and coating thickness measurement of jewelry and gold, as its digital pulse processor DPP+ significantly reduces measuring times while enabling highly accurate measurement results.

In this Application Note you will learn, among other things:

• more about X-ray fluorescence analysis of gold alloys
• which Fischer device is best suited for your application
