Temperature stability is key to achieve reliable and reproducible QCM measurements. But why is a stable temperature so important? And how will temperature variations affect your measurements? Here we explain the causes and effects of temperature related artifacts in QCM measurements.
QCM-D and ellipsometry are two surface sensitive real-time technologies that can be used in combination to give synergistic effects. To make to most of the combined output data, there are some aspects to consider when setting up the combined experiment and when analyzing the captured data.
The mass extracted by QCM-D and ellipsometry are often not the same. So, what is the difference between these masses, and why are they not equal?
The ability to take up and release water is central for many materials, such as hydrogels, whose function depend on the ability to hydrate and dehydrate. Hydration and swelling are also central when dealing with hygroscopic materials. QCM-D can be used to characterize such swelling phenomenon.
Adsorption and desorption phenomena are important to study in e.g. surface science and bio-related applications, where molecules are interacting with surfaces.
