Q-Sense develops and markets research instruments based on Quartz Crystal Microbalance (QCM) with Dissipation monitoring (QCM-D) technology.



products are suitable for studying molecular interactions and surface science, providing answers about mass and structural changes at the nanoscale level.


The QCM is based on a vibrating quartz crystal sensor (an acoustic resonator); then measurements are made of  changes in vibration frequency in response to reactions that occur on the sensor surface. Since 1999, when the first commercial QCM-D (trademarked)  instrument was created, Q-Sense has become the worlds leading supplier of acoustic resonator-based instruments. It is used in interfacial acoustic sensing. Its most common application is the determination of a film thickness in a liquid environment (such as the thickness of an adsorbed protein layer). It can be used to investigate further properties of the sample, most notably the layer’s softness.

Being a QCM, the QCM-D works in real-time, does not need labeling, and is surface-sensitive.

Q-Sense instruments are found in over 25 countries worldwide and there are currently over 750 publications citing the use of the QCM-D technology.
