A piezoelectric quartz crystal with one separated electrode that could be immersed in liquid was applied to the simultaneous determination of atropine sulphate and sodium chloride in atropine sulphate eye drops. The average relative errors were 4.0% for atropine sulphate and 2.7% for sodium chloride

An inexpensive mass and viscosity sensor can be constructed from a quartz crystal microbalance using an automatic gain control oscillator. The gain control voltage, which maintains a constant oscillation amplitude, is shown to be affected only by the energy loss to the liquid medium and the crystal

The resonance behavior and the electric equivalent circuit of the ringed-electrode piezoelectric sensor (REPS) operating in liquid phase have been studied. The results indicate that the REPS can be used to investigate a solution's properties and mass loading on a quartz surface under different condi
