QSense™ Quartz Crystal Microbalance with Dissipation

Quartz Crystal Microbalance with Dissipation Monitoring

QSense™ QCM-D Instruments

QSense QCM-D (quartz crystal microbalance with dissipation) systems enable real time monitoring of nanoscale molecular interactions and structural changes at surfaces and interfaces. Based on unique Ring-down technology that is superior to other QCMs, the QSense line allows the fastest data acquisition of any QCM on the market (up to 300 datapoints per second) and exceptional mass sensitivity (0.5 ng/cm² i.e., sub monolayer). The flexibility of this technique enables vast exploration and experimentation, making it easy to find answers to research questions in various disciplines such as Biology, pharmaceuticals, nanotechnology, polymer chemistry, electrochemistry, and food science.

The unique dissipation parameter that defines QCM-D is obtained under non-voltage conditions leading to more stable, long-term signals. With this technique, you can obtain accurate and fast measurements of surface mass and viscoelastic parameters consistently for a wide range of samples, consisting of various combinations of surfaces and sample solutions (aqueous as well as organic media).
