Precise precious metal analysis

For value-based settlements

The analysis of the precious metals in your material is the basis for a transparent and fair settlement. For this, various analysis methods are applied - depending on the material type or processing model. The latest technologies and a lab team with long-standing expertise guarantee a precise valuation.

The representative samples, which are extracted during processing, are professionally prepared and analyzed. We have a wide range of precision apparatus available to do this, including X-ray fluorescence analysis, wet chemical analysis using ICP-OES, matrix analysis, and analysis to determine moisture and carbon.

XRF

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 period of time.

ICP-OES

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 determined.

Sulphur/carbon analysis

Thanks to the separate determination of organic and inorganic carbon, we can then 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.
