MAIN APPLICATIONS 
      - adsorption kinetics, adsorption constants
      - interaction of biomolecules (antigen - antibody and others), binding constants
      - thickness and optical properties of thin organic films

ADVANTAGES 
      - SPR measurements in liquids or in gases
      - Two channels for parallel or differential measurement
      - Very low consumable costs
      - Additional analog input
      - Wide angle range (up to 17 degrees, measurements from critical angle up to more than resonance
         angle for subsequent fitting to evaluate layer thickness and its optical properties)

MORE ADVANTAGES 
       - open configuration: good for education purposes and easy adaptation for simultaneous measurements
          of SPR-fluorescence, SPR-electrochemical measurements, Surface Enhanced Raman Spectroscopy
          (SERS), AFM, SEM, FT-IR spectroscopy or other particular experimental tasks
       - easy to use (learning time less than one hour)
       - low costs (less than 10.000 EUR)
