Abstract
A new electronic design for continuous monitoring of the motional series re sonant frequency of a quartz crystal microbalance either in vacuum or in si ngle-face contact with a fluid medium is presented. The motional resistance is directly measured and a simple method for measuring L and C parameters of the Butterworth-Van Dyke equivalent circuit is described. The results ar e in agreement with impedance analyzer measurements. (C) 2000 American Inst itute of Physics. [S0034-6748(00)04806-1].
