Awards

Stefan Meisen received for his diploma thesis the Graduate Award of the Year 2003 of the University Duisburg-Essen.

Focus

His work in the pharmaceutical analytical development is focused beside the conduction of stability studies mainly on the development and validation of chromatographic analytical procedures for release of raw materials, intermediates, drug substances and drug products as well as for in-process control. These methods comprise procedures used for content and purity determinations as well as for quantification of related substances, degradants and toxicological relevant impurities.

Methods

  • Liquid chromatography (HPLC, U(H)PLC and HPTLC) with non-MS detectors (UV/DAD, FLD, ELSD, CAD, RI, ECD, MALLS)
  • Gas chromatography (GC-FID, GC-ECD und GC-MS)
  • Atomic and molecule spectroscopy
  • Varied sample preparation procedures
