What is the Sauerbrey equation?

In the context of QCM technology, there is often a reference to the so-called Sauerbrey equation. Here we explain what this equation is, and when it should be used.

What is a biomaterial?

The concept ‘Biomaterial’ is fairly frequently encountered. Here we explain what defines a biomaterial, and where this category of material is used.

What is dissipation?

Talking about QCM-based instrumentation, one often comes across the concepts of ‘dissipation’ or ‘damping’. Here we explain what these concepts mean, and why are they relevant.

How to measure swelling of thin films with QCM-D

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.

How to measure surface adsorption and desorption with QCM-D

Adsorption and desorption phenomena are important to study in e.g. surface science and bio-related applications, where molecules are interacting with surfaces.

How to measure thin film degradation with QCM-D

Thin film degradation and material desorbtion is sometimes wanted and sometimes not. In both cases, it can be important to characterize so that it can be optimized and controlled.

What can QCM-D technology be used for?

Surfaces are all around us. To control the macroscale we need to understand and tune the nanoscale. To our aid, we use analytical tools, such as QCM-D

What is QCM-D?

QCM-D (Quartz Crystal Microbalance with Dissipation monitoring) is an extended version of QCM, and is particularly suitable for the characterization of soft layers.

What is QCM?

Quartz Crystal Microbalance, or QCM, is essentially a balance for very small masses which enables time-resolved characterization of thin and rigid layers.
