摘要

The impedance characteristics of the quartz crystal used in quartz crystal microbalance is considered a higher dimension of information that can be obtained in addition to the resonant frequency change of the crystal. The impedance allows calculating the quality factor of the oscillator that is very closely related to the mechanical rigidity of the material, which is adsorbed or deposited on the quartz crystal. This paper concentrates on utilizing an impedance analyzer, often found in electroanalytical laboratories. instead of the Usually required network analyzer.
