eQCM-I Mini 电化学石英晶体微天平

with Impedance Measurement and Dissipation

The eQCM-I MiniTM Quartz Crystal Microbalance is a high-sensitivity mass sensor which measures the change in frequency and dissipation of a quartz crystal resonator and any adsorbed film.  eQCMs are useful in any number of applications because you combine electrochemical measurements with mass measurments to gain further insight into what drives mass changes (and elasticity changes) within 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 in the United States and China. Inquiries outside of the US and China can go directly to MicroVacuum (http://www.owls-sensors.com/contactus). 

The resonant frequency and the bandwidth of the resonant conductance curve are determined. The bandwidth or full width at half maximum, (FWHM) is direct correlation with the quality factor (Q) which is by definition the inverse of the well known dissipation (D).

eQCM-I Mini Features:

·         Both the frequency and the quality of resonance (FWHM or bandwidth or dissipation) are measured

·         Different harmonics (up to the 13th overtone at 5MHz crystals) can be quickly and sequentially measured

·         Temperature control from 4°C to 80°C (± 0,02 °C) is included

·         EC measurement module is optionally available with ITO-QCM sensors

·         Modular sensor holder up to 4 measuring channels

·         External PC with Windows® 10; communication with QCM-I via USB
