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 verified by means of stamped-in inspection stamps. An analysis required for this in advance should be precise, fast and non-destructive. The measurement time required and the maximum possible throughput are also important. The new FISCHERSCOPE® X-RAY XDV®-SDD is ideally suited, as its digital pulse processor DPP+ significantly reduces the measuring times and at the same time provides a highly precise analysis. Trust and reliability are of great importance in the precious metal business. Hallmarking plays an important role. For this purpose, the proportion of gold or other precious metals in the alloy of precious metal bars, jewelry or other pieces is determined by official testing agencies and confirmed by embossed fineness stamps. In the case of precious metal bars, their homogeneity is also frequently analyzed at various points. Because only those who know the exact precious metal content are able to make a safe decision about the price to be achieved regarding the very volatile pecious rate.
