Quartz Crystal Microbalance with Impedance Measurement and Dissipation (QCM-D)
The eQCM-I MiniTMQuartz Crystal Microbalance measures the changes in frequency and dissipation of a quartz crystal resonator and any adsorbed film. eQCMs are high-sensitivity mass sensors, useful in any number of applications - biosensors, chemical sensors, corrosion, polymer films, nanoparticle films, protein films, biofilms, etc. Coupling a QCM with a potentiostat allows you to drive electrochemical reactions within the film, thereby producing mass changes. Combining mass changes with chemical changes allows you to more fully characterize your films.
The QCM-I, QCM-I Mini, and eQCM-I Mini are manufactured by MicroVacuum Ltd. (http://www.owls-sensors.com/) of Budapest, Hungary. MicroVacuum has integrated control of our USB-based potentiostats into their BioSense software (V3 or higher). Gamry has partnered with MicroVacuum for distribution of these instruments.
