Further Analytical Methods

Further physical and chemical characterizations can be determined by subsequent analytical methods. These include the analysis of surface tensions (tensiometry), of absorption behavior of UV and visible light (UV/VIS spectroscopy) and viscosity (rheology) of liquids, as well as detection of radicals (electron spin resonance), the investigation of thin films (ellipsometry) and others.




Spectroscopic and imaging ellipsometry

UV/VIS Spectroscopy

UV/VIS spectroscopy can be used for detection and quantification of UV/VIS absorbing substances, e.g. unsaturated organic substances: For the detection of contaminants on surfaces, they are rinsed off with a suitable solvent and measured in solution.





Oscillating Quartz Microbalance with Dissipation Measurement

Investigation of mass changes by revising the resonance frequency of a vibrating quartz crystal, e.g. for the determination of protein adsorption and desorption on surfaces.


Volumetric sorption analysis
