Physicochemical Analysis

Dr. Hanna Hartmann
Head of Biomedicine & Material Sciences

In the field of biomedicine and material sciences, we offer a wide range of testing services for medical implants.

Those are:

Material characterization

  • Topography: characteristic structures, defects
    • SEM, white light confocal microscopy, AFM
  • Coating analysis: Thickness, cross-section, coating sequence
    • FIB, SEM, TEM, ellipsometry
  • Active ingredient distribution on surfaces
    • Raman
  • Chemical characterization (based on ISO 10993-18): Influence of production, storage, degradation, etc.
  • XPS, FTIR, Raman, SNMS
  • Surface wettability


Evaluation of coating processes

  • Analysis of structure and thickness of layer
  • Testing of surface wettability and topography
  • Testing of degradation kinetics and degradation products based on ISO 10993-13, ISO 10993-15
  • Analytics for drug release


Mechanical checks

  • Static material and component tests (tension, compression, bending, shear, peel)


Corrosion tests

  • Corrosion resistance (based on ISO 10993-15 and ASTM F 2129)
  • Degradation products from metals and alloys (based on DIN EN ISO 10993-15)
  • Surface analysis (light, scanning electron microscopy)


Degradation investigations

  • Release/degradation (mechanism and kinetics) of thin polymer layers based on DIN ISO standard 10993
  • Detection of degradation products: qualitative and quantitative (based on ISO 10993-13, -15, ISO 13781; e.g. polarography)
  • Degradation kinetics (sample and fragments)


Testing for cleanliness

  • Comparison with standard surfaces
  • Filmic contamination and particles
