Research statement

Our group develops advanced process concepts, in particular for challenging separation problems. Special focus is on developing novel, high performance processes for difficult and extremely challenging separations. Such problems are found, for example, in the production of pharmaceuticals, biotechnological products, polymers, and fine chemicals.

Investigated technologies comprise, among others,SSR (lab)

  • Chromatography (preparative and analytical; all relevant modes including advanced concepts like simulated moving bed, steady-state recycling, etc.),
  • Membrane processes (like ultra- and nanofiltration, reverse osmosis, and electro-dialysis),
  • Crystallization,
  • Gas adsorption (including PSA and alike).

Application areas are enantioseparations, gas purification, downstream processing of biomolecules, and nanoparticle classification.

Of special interest for us are integrated and reactive separation processes, where we purposefully combine different separation techniques with each other, or with (bio)chemical reactions. Here we systematically develop not only new process concepts, but also computer-based methods and tools for their optimal design and development.

Equipment (selection)

  • Preparative chromatography systems for RP, NP, SEC, chiral chromatography, ion chromatography, ...
  • Membrane test rigs (UF, NF, RO)
  • Electrodialysis unit
  • Analytical HPLC systems (detection by UV, DAD, CAD, MS)
  • Tandem ion chromatography unit coupled to HPLC and MS (trace analysis for mixtures of uncharged and ionic compounds)
  • Gas chromatography
  • Magnetic suspension balance
  • Mass spectrometer
