Stationary solution voltammetry cell for simultaneous electrochemical response and QCM sensing. Universal design compatible with both 14 mm and 25.4 mm diameter quartz sensors.

A thin film of measured material is deposited directly onto the upper electrode of the QCM sensor or dispersed in an electrolyte. Counter and reference electrodes are mounted in a top casing (2- or 3-electrode setup). Cell elements are constructed from materials inert to the sample (glass and PEEK).

Application note

EQCM allows studying changes in interfacial mass and physical properties associated with electron transfer processes at the electrode surface, such as those accompanying electropolymerization of thin films. The reference electrode tip should be placed close to the QCM sensor upper electrode (3-5 mm) to ensure negligible potential drop for low-current experiments. Various auxiliary electrodes are suitable including metal wire, metal foil, and graphite rod electrodes. Gas bubbling must be stopped prior to experiment.
