Surfactants are central to many interface related applications, from cleaning to reaction inhibitors. Measurement possibilities include:

  • The effectiveness of surfactants used in detergents can be evaulated by observing how, for example, lipid films are removed
  • Adsorption and desorption kinetics of surfactants can be monitored in real time
  • Distinguish between aggregates and monolayers thus evaluating the function of surfactants
  • Thanks to the Dissipation, morphological changes in the surfactant film can be traced
  • Characterize the thickness and hydration of surfactant films
  • Various types of surfaces - metals, polymers, functionalized and even nano-structured coatings - can be employed

Please find application notes on your right.
