Analysis of Precious Metals
About Analyses
One of our analytical specialities is the analysis of the precious metals Ag, Au, Pd, Pt, Rh. The rarer metals Ir and Ru are also among our regularly analysed precious metals.
The Following is an Overview of our Focus Analysis:
Ores: Here, the natural precious metal deposits such as gold (Au), silver (Ag), platinum (Pt), palladium (Pd) and others are determined or the quantitative composition of the ore is determined. We also analyse enriched ores for precious metals. In a broader sense, this includes concentrates, which are mainly analysed for Au, Pt and Pd.
Intermediates: These very diverse samples are analyzed for a wide variety of elements.
Metallurgical products: In most cases, this involves complying with requirements and specifications and adhering to limit values.
Reject material and dental dross: Fine preparation is often necessary before analysis. We then usually analyse these samples for Au, Ag, Pt, Pd and, in the case of dental dross, also for mercury (Hg).
Electronic scrap: We receive it as a ready-prepared sample and as a raw sample, which still has to be prepared in our preparation department before being analysed. This is followed by analysis for copper (Cu), Au, Ag, Pd, sometimes also Pt or other metals such as indium (In), nickel (Ni), tantalum (Ta), tin (Sn), antimony (Sb).
Catalytic converters: They can be used in many different ways, which also determines their composition: We analyze both automotive exhaust catalysts and industrial catalysts. While Pt, Pd and rhodium (Rh) are always determined for the former, industrial catalysts are Pt, Pt/rhenium (Re), molybdenum (Mo) etc., which need to be analyzed.
Fine metals and alloys: Analysed here are Cu, Au, Ag, Pd, Pt, brass (CuZn), bronze (CuSn), aluminium (Al), nickel (Ni), tungsten (W), cadmium (Cd), In and much more.
Pure metals and their stock solutions with metrological traceability are used for all analyses. In addition, we use certified reference material, in whose international certification IMG is also involved.
Thanks to our repeated and successful participation in national and international interlaboratory tests, we are able to continuously monitor the accuracy of our results.
Frequently Asked Questions (FAQ)
Which precious metals can you analyze?
We analyze gold, silver, platinum, palladium and other valuable metals that may be contained in various products and alloys.
How accurate is precious metal analysis?
Thanks to state-of-the-art analysis methods such as XRF and spectrometry, we deliver extremely precise measurement results with a very low deviation.
Do you also offer analyses for large quantities?
Yes, we analyze both individual items and larger batches for retailers, companies and recycling companies.
How can I send in my precious metals for analysis?
You can send us your samples by post or bring them to our laboratory in person. We can also organise safe collection on request.
How long does the analysis take and when will I receive the results?
The processing time is usually 1-3 working days. You will receive the analysis results by e-mail or in written form on request.
