High precision dissipative electrochemical quartz crystal microbalance

EQCM-I MINI Electrochemical Quartz Crystal MicrobalanceIt is a highly sensitive mass sensor based on impedance analysis of quartz chips, which measures the resonance frequency and the bandwidth or full width at half maximum (FWHM) of the resonance conductivity curve. They are directly related to the quality factor Q, which is the reciprocal of the dissipation factor D.

This product can measure the frequency changes and energy dissipation of quartz chips or adsorbed thin films, and then analyze small changes in mass and adsorption layer thickness during the reaction process; Be able to determine the rigidity or flexibility of the membrane and analyze its viscoelastic properties; And real-time tracking of molecular arrangement, structural changes, and other processes.

Simultaneously measure resonance frequency and dissipation factor

Quickly measure multiple harmonic vibration frequencies (for 5MHz chips, the 13th harmonic can be measured)

Realize integrated design with Gamry electrochemical workstation
