Abstract :
A frequency/voltage conversion circuit for alternating current electrogravimetric measurements based on quartz crystal microbalance oscillators is proposed. This circuit improves the sensitivity and the bandwidth of the conversion systems proposed until now. Static and dynamic calibration results of the circuit are reported. These results prove its reliability for alternating current-electrogravimetric measurements and will allow the development of new applications in various electrochemical fields.
