The analytical laboratory offers complete characterization of ion-exchange membranes and materials.

Characterization of input materials and ion-exchanger for production of ion-exchange membranes

  • Measurement of the ion-exchanger swelling
  • Measurement of the ion-exchange capacity of ion-exchanger (IEC), granulate, membrane foil (MF), ion-exchange membranes (IM)
  • Measurement of the ion-exchanger humidity after drying operation
  • Measurement of the ion-exchanger humidity after grinding operation
  • Measurement of the size distribution of the ground ion-exchanger particles

Characterization of ion-exchange membranes (IM)

  • Sheet and specific resistance of IM
  • Permselectivity, anti-ion transference number of IM
  • Microscopic examination
  • Hydraulic permeability
  • Physical properties of IM (change of weight, length, width and thickness in the dry and wet conditions)

Processing of measured data in the form of final reports and statistical evaluations

  • Expert collaboration with specialists from universities and cooperating institutions (Institute of Chemical Technology Prague, Institute of Macromolecular Chemistry of the Academy of Sciences of the Czech Republic Prague, Institute of Inorganic Chemistry of the Academy of Sciences of the Czech Republic Prague, University of Pardubice)

Laboratory equipment

  • Gas chromatograph (GC)
  • Emission spectrometry with inductively coupled plasma ICP-OES
  • FTIR – infrared spectrometry
  • Highly efficient liquid chromatography HPLC ION CHROMATOGRAPHY (IC)
  • Rotational rheometer
  • Microwave mineralizer
  • Potentiostat
  • Porometer
  • Zeta potential analyser
  • System for measurement of permeation properties of membranes developed for gas separation (permeameter)
  • System to analyse gas mixtures (mass spectrometer)
  • Scanning electron microscope

Besides the above mentioned complex analytic instruments, the laboratory is fitted with standard equipment (scales, muffle furnace, rupture machine, laboratory vibration press etc.).
