Gold, Precious Metals, Jewellery, Watches and Accessories Professional Measurement Technology for Analysis, Valuation and Authentication of Precious Materials Coating Thickness Material Analysis Material Testing

Metrological Solutions from FISCHER Precision and reliability for the most sophisticated demands Gold and precious metals have always held special appeal. Whether the objects made of these materials serve only aesthetic purposes or should perform some technical function, verification of the asserted quality and genuineness requires a precise and, above all, non-destructive measurement method. From quick valuation and authentication to high-precision material analysis – FISCHER offers the right measurement technology. Knowledge, Competence, Experience Since 1953, FISCHER has created and produced...

Cash for Gold – Non-Destructive Evaluation Fast and dependable analysis of jewellery and precious metals Analysing the Authenticity of Gold Bullion Due to the skyrocketing prices of precious metals in recent years, counterfeit gold bars have begun appearing with increased frequency. Measuring the electrical conductivity is used to verify the genuineness of ingots non-destructively, and thus without loss in value. This method exploits the physical effect that fine gold, various alloys and impurities all differ in their electrical conductivity, thus allowing ingots of specific alloys or fine gold...

High Precision Analysis and Certification of Precious Metals Solutions for refineries, assay offices and hallmarking institutes Gold and Precious-Metal Certification Instruments used in assay offices and hallmarking institutes for material analysis of gold and precious metals must meet the strictest of specifications. 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 analysing precious...

A Range of Measurement and Analysis Applications on High-Quality Watches Precision calls for precision Precious Metal Coatings on Watch Hands and Other Parts Watch hands, faces, gear wheels and other visible elements inside high-quality watches are often plated with gold or other precious metals that lend the watch its elegant look. Here, not only is the visual effect important but also the precise functioning of the parts. Tight tolerance limits require extremely precise coating thickness measurements, such as those achieved using X-ray fluorescence. Gold Coating Measurement in the Watch Industry...

Coating Thickness Measurement for Quality Assurance In addition to select fashion jewellery, high-end fountain pens, glasses frames and accessories are often coated with precious metals. It is necessary to maintain a certain coating thickness for the surface to be able to withstand everyday influences like abrasion, skin oils and sweat. Precise quality control of the applied coatings is simple using the FISCHERSCOPE X-RAY XAN 222 or XDAL. Alloy Analysis of Materials Used Metal parts on clothing, closures and buckles on belts and handbags - these items are generally made of various alloys, the...
