with Impedance Measurement and Dissipation (QCM-D)
The QCM-ITM Quartz Crystal Microbalance measures the changes in frequency and dissipation of a quartz crystal resonator and any adsorbed film. QCMs are high-sensitivity mass sensors, useful in any number of applications - biosensors, chemical sensors, corrosion, polymer films, nanoparticle films, protein films, biofilms, etc. These changes in frequency and dissipation give information relating to changes in mass, viscosity, and elasticity of 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.
