Q-Sense E4 instrument employs Quartz Crystal Microbalance with Dissipation Monitoring (QCM-D) technique. By tracking mass changes and viscoelastic properties of thin-film deposits formed on a standard gold-coated quartz crystal microbalance sensor, QCM-D measurements can be used for studies of surface and surface-bound processes such as adsorption, cross-linking, aggregation, swelling, dissolution, corrosion, etc. The flow modules permit flowing liquid or gas as a medium being in contact with the sensor. 4-line peristaltic pump ensures stable liquid flow rate in both directions.
This is an accordion element with a series of buttons that open and close related content panels.
