Analytical and materials testing Laboratories.

We work with modern technology.

Our tasks in the Cendres+Métaux laboratories include the definition and testing of new materials, verifying the quality of alloys and materials, establishing the fineness of jewellery alloys, establishing the fineness of waste containing precious metals and investigating complaints.

Our chemists, physicists, metallurgists, sworn precious metal assayers and laboratory technicians work with state-of-the-art systems and comply with internationally recognised standards. The most important procedures have been accredited by the Swiss Accreditation Service in accordance with ISO/IEC 17025 and are registered under STS 174. In addition, the analytical laboratory is regularly inspected by the Swiss Precious Metals Control authorities.

The accreditation indicates that our skills are recognised by the Accreditation Services. It shows that our laboratories make independent testing decisions, employ qualified staff, work with validated methods and are able to trace the tested merchandise back to the test results.

Therefore, we make a substantial contribution to the application of medical products and precious metal control legislations and can guarantee the conformity of our products and the reliability of our accounting analyses.

Our different analysis processes:

  • X-ray fluorescence spectrometry (XRF)
  • Cupellation (fire assay)
  • Inductively coupled plasma optical emission spectrometry (ICP-OES)
  • Potentiometric titration of silver

  • Quantitative analyses by sworn precious metal assayers
  • In-house materials testing: - own, accredited metallurgical and analytical laboratories ISO/IEC 17025
  • Certification: ISO 9001 and environmental management system ISO 14001
