QCMD 400
Multichannel Quartz Crystal Microbalance with Dissipation system for sensitive real-time surface interaction and thin film analysis.
-Multichannel measurement on 4 sensors simultaneously—significantly increases throughput and saves experimental time.
-High sensitivity in both frequency and dissipation—enabling precise mass and viscoelasticity determination.
-Individual control of conditions for each channel—temperature, flow rate, and solution can be tailored per cell.
-QuickLock cell for easy sensor placement with a transparent lid for sample view during measurement.
-HFF-QCM optional modules for very high sensitivity and low sample volume flow cells.

Description
The BioNavis QCMD 400 is an advanced Quartz Crystal Microbalance with Dissipation (QCMD) instrument that allows simultaneous real-time, label-free monitoring of surface and thin film interactions across four independent channels. Using piezoelectric quartz resonators, it detects minute changes in resonant frequency and energy dissipation as molecular or material layers interact with sensor surfaces. This dual measurement (frequency + dissipation) provides detailed information on both mass changes and viscoelastic properties of layers, applicable in fields ranging from biomaterials and biosensors to coatings and surface science.
