Characterisation of Nanoscale Systems (NanoSys)

The NanoSys Platform offers physico-chemical methods to determine the sizes of nanoparticles and inner surfaces of nano- or mesoporous solids. They belong to the research groups of Prof. Smarsly (chemistry) and Prof. Klar (physics):

  • Nanotracking Analyser - Malvern Instruments Ltd. Nanosight, size range approx. 10 - 1000 nm.
    Person in charge is / group of Prof. Klar.

  • Nanoparticle Analyser - Malvern Instruments Ltd. Zetasizer Nano ZS, with dyn. and stat. light scattering, measurement of particle size (range approx. 0.3 nm - 10 µm) and molecular weight.
    Person in charge is / group of Prof. Smarsly.

  • Ultra Disc Centrifuge - CPS Instruments Inc. 24000 DC, with dyn. light scattering, size range approx. 10 nm - 40 µm.
    Person in charge is / group of Prof. Smarsly.
  • Mercury Porosimetry - Thermo Fisher Scientific, PASCAL 140/440, Intrusion in the range from 0,01 kPa – 400 MPa for pore size (3,5 nm – 60 µm diameter) and pore volume determination.
    Person in charge is / group of Prof. Smarsly.

  • Physisorption -  Quantrachrome Quadrasorb evo, for measurement of BET surfaces, pore volumes and pore-size distributions (mesopores), using nitrogen sorption at 77 K.
    Person in charge is / group of Prof. Smarsly.

  • Physisorption -  Quantrachrome Autosorb-iQ, with turbo-molecular pump for the analysis of micro-/nanopores or very small surface areas, using sorption of nitrogen, argon or krypton.
    Person in charge is  / group of Prof. Smarsly.
