Material Analytics

We offer classic and innovative chemical analysis for customers from a wide range of industries. The core areas of our R&D services are ultratrace analysis in high-purity materials, chemical characterization of surfaces and interfaces, as well as thermo-mechanical and chemical analysis of polymer materials. In the area of special analytics we investigate gas permeation e.g. through barrier films and membranes as well as the influence of various aging processes on polymer properties.

Companies with a need for high-purity materials, e.g. from the semiconductor industry, photovoltaics, laser optics, laminated glass production and many more, benefit from our support. Depending on customer requirements, we offer simple analytical services as well as root cause analyses and complex problem solutions.

Our expertise includes:

  • Trace analysis in volume and on surfaces
  • 2D mappings of the element distribution
  • Characterization and evaluation of polymer materials
  • Permeation measurements and accelerated aging
