Instrument description :

The QCA922, an instrument developed for piezoelectric gravimetry in the ng-μg regions, monitors both the resonant frequency and resonant resistance of a Pt, Au or C coated AT-cut quartz crystal. The resonant frequency changes with the effective surface mass on the crystal, and the resonant resistance changes with the viscosity of the material interfacing with the surface of the quartz crystal. Capable of covering a wide range of applications, the QCA922 was developed primarily for applications where it is used in conjunction with a potentiostat/galvanostat as an Electrochemical Quartz Crystal Microbalance (EQCM).

With the addition of a potentiostat/galvanostat, the QCA922 system (with the Pt, Au or C coated resonator serving as the working electrode) can provide information on potential, current, charge, resonant frequency (mass), and resonant resistance (viscosity) simultaneously. This allows researchers to analyze electrochemical depositions, polymer films formation on electrodes, corrosion, adsorption and electrochemical reaction mechanisms. Other application areas include battery research, electroplating and biosensor development.
