Quartz crystal microbalances

Quartz crystal analyzers (also called quartz crystal microbalances, EQCM), in combination with a potentiostat, allow for precise measurement of very small mass changes as a function of electrode potential and current during electrochemical experiment. These devices measure the resonant frequency and resonant resistance of quartz crystal with sputtered working electrode, thus giving the ability to measure very small changes in the mass of the electrode, f.ex. controlling thickness of electropolymerization or metals electrodeposition.
Quartz crystal microbalances can be connected to offered Bio-Logic potentiostats and record data directly to the analytical software.

    Quartz crystal analyzer QCM922A monitors both the resonant frequency and the resonant resistance of quartz crystal with sputtered electrode. Both signals are also reflected on the two analog outputs. It is possible to connect this quartz crystal microbalance to a Bio-Logic potentiostat using a DB9-8BNC cable (ref: 092-22/1).
