Follow Nanoscale Molecular Interactions and Surface Phenomena 

Q-Sense is a line of analytical instrumentation based on Quartz Crystal Microbalance with Dissipation monitoring (QCM-D) technology. This technology enables nanoscale mass and structural changes to be measured and therefore offers a robust method for studying molecular interactions and surface phenomena. Measurements are based on changes in vibration frequency of a quartz crystal sensor (an acoustic resonator) in response to interactions or reactions occuring on the sensor surface. The product range includes fully automated systems as well as flexible set-ups with specialty modules together with a wide range of sensor coatings.

Q-Sense – the World Leader in Quartz Crystal Microbalance

Since 1999, when the first commercial QCM-D instrument was created, Q-Sense has become the world leader in Quartz Crystal Microbalance based instrumentation. Today Q-Sense instruments can be found in over 25 countries worldwide and QCM-D technology has been published in over 1700 publications. Q-Sense has been part of Biolin Scientific since 2003.

What Our Customers Are Saying

Our customers work in both large and small corporations, universities and colleges, academic institutions, public and private research, test agencies, and in technology and knowledge transfer centers.  Our customers have the curiosity and drive needed to do research at the forefront of science.

The versatility of the QCM-D makes it the workhorse instrument in our laboratory. In fact, we found it so useful that we purchased two instruments.
– Professor Lynn Penn, Drexel University, USA

Q-Sense has, by far, the most friendly and helpful customer service that we deal with on a regular basis.
– Professor Rick Davis and his student Will Miles, at the Department of Chemical Engineering, Virginia Tech, USA

The QCM-D instrument was an obvious choice to assess the wet mass and composition of the lipid that we were using to create the membrane.
– Dr Lisa Martins at Monash University, Victoria, Australia

[QCM-D] also provides key information about the effects of solvent coupling that otherwise are difficult to access with other tools. Data interpretation may be challenging, but combined with other experimental approaches, it can be very useful and revealing.
– Professor Orlando Rojas, at North Carolina State University, USA

At Unilever we are interested in how surfactants work and their interaction with polymers. This is why QCM-D is an important part of our technical arsenal.
– Dr Jordan Petkovs, Unilever, UK

I guess everybody in the QCM-D community is well aware of the tremendous versatility of the flow chamber system for these studies.
– Dr Alex Welle, Institute for Biological Interfaces, Karlsruhe, Germany

We have relied heavily on our QCM-D data to interpret the response of contacting liver cells. […] We will continue to extensively use the QCM-D as these studies progress.
– Jennifer Phelps, Yale University, USA
