Characteristics of Dependence on Immersion Angle of a One‐Face Sealed Quartz Crystal Microbalance in a Newtonian Liquid

Abstract

In order to obtain insight into the effect of the immersion angle θ of the one‐face sealed quartz crystal microbalance (QCM) in a Newtonian liquid, we investigated the effect of the direction of the electrode of the one‐face sealed QCM, and the effects of the air–liquid interface and the sides of the cell. In the effect of the direction of the electrode of the one‐face sealed QCM, the direction of the electrode was mounted at the lower and the upper sides. This experiment showed that the direction of the electrode did not affect the resonant frequency shift Δf. In the effects of the air–liquid interface and the sides of the cell, it also became clear that those effects were negligible in our experimental conditions. Furthermore, from the present experiments, we found that only when the immersion of the one‐face sealed QCM had the element of the vertical direction, Δf deviated from the theory described by Kanazawa–Gordon. On the basis of the experimental results, we also presented the simple model of Δf of the one‐face sealed QCM.
