Chemical Analysis of Precious Metals and other Metals in Raw Materials and Recycled Materials

We are certified according to DIN EN ISO 9001: 2015

Company Profile:



In 1977 the company was founded first as a single enterprise, since 1994 it has been running under the name of Institute of Materialprüfung Glörfeld GmbH (IMG).

We are an independent and neutral company offering for the chemical analysis. Our analyses are mainly focussed on the analysis of accurate content of precious metals such as gold (Au), silver (Ag), platinum group metals (PGMs)* as well as important base metals such as copper (Cu), nickel (Ni), tin (Sn), zinc (Zn), lead (Pb), chromium (Cr), iron (Fe), cobalt (Co), antimony (Sb), arsenic (As), bismuth (Bi), tantalum (Ta), cadmium (Cd), molybdenum (Mo), etc..

*PGMs comprise platinum (Pt), palladium (Pd), rhodium (Rh), iridium (Ir), ruthenium (Ru), Rhenium (Re) and osmium (Os).

We also offer the analysis of the rare earth metals such as lanthanum (La), cerium (Ce), samarium (Sm), neodymium (Nd), etc.

The analysis of pure metals and the impurities in ultra-trace to matrix elements are also offered. Now this is done by our sister company Element Mass Spectrometry Services, Elmaspecs, GmbH, Willich.

We mainly work for industry, metal and raw material tradings, recycling companies as well as for research institutes, universities and private customers.

The main analysis areas are: Chemical analysis of ores, metals, raw and recycling materials.


Professional qualifications:

Our authorized representative, Mr. Wolfgang van Leeuwen (Dipl.-Lab.-Chem), is publicly appointed as sworn expert by the regional Chamber of Industrie and Commerce (IHK) for chemical analysis in commercial purposes. Under his supervision we are able to run routine and umpire analyses of the elements Au, Ag, Pt, Pd, Rh, Ir, Ru and Cu.

We are a member of the German Association of Metallurgy and Miners (GDMB), where we participate in the working groups “Copper”, “Precious Metals” and “Special Materials” of the committee of chemists in

  • the production of certified reference materials and
  • the development of new analytical methods.

Every year we regularly participate in national and international round robin tests.
Accordingly other activities are carried out for industry, private sector and for courts based on our experience.
We are also available for consultation.
