RQCM – RESEARCH QUARTZ CRYSTAL MICROBALANCE
OPERATION
3-8
Face Connector on the RQCM is connected to the potentiostat’s “working electrode” port. A
typical cyclic voltammetric (EQCM) experiment would involve the application of the
electrochemical waveform to the working electrode and the simultaneous measurement of the
current flowing through the electrochemical cell and the oscillation frequency and series
resonance resistance of the crystal.
Figure 5 is an example of a typical voltammogram plot obtained from the INFICON RQCM with a
PC. This particular experiment involved a 0.1 M solution of CuSO4 in 0.5 M H
2
SO4, using a 5
MHz, 1 inch diameter, polished, gold coated crystal mounted in a CHC-100 Crystal Holder as the
working electrode.
