Flexible quartz crystal microbalance system

Explorer from QSense

The Explorer  from QSense is a compact design QCM-D for one flow module, holding one sensor. It is temperature controlled and samples are introduced by using a peristaltic pump included in the system. An optional electrochemistry cell is available making it possible to combine QCM-D and electrochemistry measurements. A window module is also available for optical access to the crystal during measurements, enabling e.g. a combination of microscopy and QCM-D as well as a Ellipsometry module.

Flexible choice of surfaces
Flexibility, combination with microscopy and ellipsometry
Measuring molecular interaction

QCM-D can detect and quantify during the binding of small molecules for example the antigene antibody interaction as well as conformational changes in proteins.

Thickness measurements of adhesion layers on surfaces

Molecules such as prolymers bind to surfaces. With QCM-D a quantification of the thickness of such layers can be made.

Desorption measurement

Cleaning properties of detergents can be measured in real time.
