QCM-D for analyzing cleaning of hard surfaces

- How to assess thin film degradation and cleaning efficiency using model stains

An area where material degradation and removal are highly desired is in the contect of cleaning. Particularly, it is relevant to characterize and optimize the soil removal with respect to target materials and cleaning conditions.

In this application note we show how soil degradation and removal can be characterized, and how the cleaning efficiency can be assessed, with QCM-D.

In this application note you will find:  Thin film degradation

  • Experimental setup
  • Real-time characterization and quantification of soil removal
  • Comparison of several different conditions: varying soils, temperatures, surfactants, and surfactant concentrations.
