Instruments used in assay offices and hallmarking institute for material analysis of gold and precious metals must meet the strictest of specification. Besides gold content analysis, it is necessary to be able to determine other precious metals or prohibited substances. Well established in the industry, X-ray fluorescence analysis offers an excellent alternative to the widely-used fire assay method (cupellation) for analyzing precious metals and their composition – without damaging the item. The high end measurement system FISCHERSCOPE X-RAY XAN 250 was developed specifically for high precision analysis of precious metals as required for hallmarking and assay offices.
