To ensure the constant monitoring and improvement of our processes, we actively participate, as a member of the professional association “Gesellschaft der Metallurgen und Bergleute e.V.”, in the following committees: Working Committee for Precious Metals, Working Committee for Special Metals and Working Committee for Copper. In addition to the exchange of information, an important area of activity of these committees is the regular performance of inter-laboratory analyses from the relevant areas. We are also a member of the IPMI (International Precious Metal Institute) and take part in regular inter-laboratory analyses.
