The QCM-I dissipative quartz crystal microbalance is a highly sensitive mass sensor based on impedance analysis of quartz chips. It measures the resonance frequency and the bandwidth or full width at half maximum (FWHM) of the resonance conductivity curve, which are directly related to the quality factor Q, which is the reciprocal of the dissipation factor D. $n $n - Impedance type, dissipative type quartz crystal microbalance
