Electrochemical studies with the quartz crystal microbalance.
Gafin, Anthony Harold
A quartz microbalance electrode (QME) was constructed for the investigation of the electrochemistry of electroless plating baths. To this end, the electronic oscillator circuitry required for the microbalance was developed from literature examples, and the techniques of forming electrodes and mounting the crystal in an appropriate holder were established. The device thus developed was compact, allowing for in situ frequency and electrochemical measurements to be made in a commercially available 100 mL Metrohm cell. The precision .and accuracy obtained with the home-built device were shown to be adequate for electrochemical research, and the sensitivity was found to be consistent with the value expected from the Sauerbrey equation.(Abbreviation abstract)
