Precise precious metal analysis

For value-based settlements

A small and effective team of chemical specialists is responsible for analysing your materials to determine the precious metal content. Our well equipped laboratory has state-of-the-art technology designed for this purpose. The representative samples, which are extracted during processing, are professionally prepared and analysed. We have a wide range of precision analyses available to do this, including X-ray fluorescence analyses, wet chemical analysis using ICP-OES, matrix analyses, and analyses to determine moisture and carbon.

Our analytical methods

For precise determining precious metals contents
X-ray fluorescence analysis is one of the most frequently used methods for determining the composition of a material sample. After processing, the finely ground homogeneous powder is pressed into tablet form with a binding agent. The composition of the sample is determined quantitatively and qualitatively using X-rays. This means that reliable results are available for the precious metal content in a very short time.
Docimasy is a dry chemical process used in precious metal analysis. The powder containing precious metals is mixed with a collector metal and additives and smelted at high temperatures. During the smelting process the precious metals are concentrated in the collector metal. Impurities are slagged and can then be separated from the precious metal concentrate. The ensuing metal core is then prepared for ICP-OES analysis.
The precious metal content can be accurately determined using wet-chemical analysis methods, e.g. ICP-OES (inductively coupled plasma with optical emission spectrometer). To this end, the homogeneous powder is converted to a liquid sample. The elements contained within it are then separated and a plasma flame can be used to make them visible. The relevant precious metal contents can then be picked out.
Sulphur/carbon analysis
Thanks to the separate determination of organic and inorganic carbon, we can trace back to carbides. This method is also suitable for determining sulphur and organic carbon compound loads in carrier materials. We need to know this so that we can correctly calculate the aggregates in the plasma smelting furnace or determine whether the material is suitable for smelting.
