Installed Base




After years of practical experience and theoretical knowledge gained from studying and professional training, managing directors Rolf Eichelberg and Werner Kientopf, established SIM GmbH in 1997. Both had been researchers and developers in major German companies in the field of gas and liquid chromatography. Their vast knowledge of mass spectrometry and process analysis, and their personal commitment and continual effort form the foundation of the company’s continuing expansion.

Healthy Growth in Germany

Meanwhile with 26 highly-skilled jobs, we give a clear commitment to Development and Research in Germany. Yet the number and quality of our tasks is always increasing. The company initially focused on the production of special adapters, however meanwhile the development of high-tech equipment for gas and liquid chromatography, is an essential pillar of SIM GmbH.

In addition, we provide our customers with individual and tailor-made chromatographic solutions for issues in the laboratory, as well as in process analysis. After working in Moers and Mülheim, SIM GmbH has now found its home in the new, spacious headquarters in Oberhausen.
