EQCM 14 mm or 25.4 mm dia., 15 mL - Electrochemical Quartz Crystal Microbalance cell
This is a stationary solution voltammetry cell for simultaneous measurements of electrochemical response and Quartz Crystal Microbalance sensing. It is a universal EQCM cell that works with both standard sizes of quartz sensors, either 14 mm or 25.4 mm in diameter. In this configuration, a thin film of measured material is deposited directly onto upper electrode of a QCM sensor or dispersed in an electrolyte. The counter and reference electrodes are mounted in a top casing (either 2-, or 3-electrode setup). The cell elements are constructed with materials that are inert to the sample (glass and PEEK). It well fits aqueous (FKM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight and can be used when the removal and exclusion of contaminants such as oxygen and water is required by bubbling of an inert gas through the electrolyte.
EQCM allows studying changes in the interfacial mass and physical properties associated with electron transfer processes occurring 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), where the working electrode is exposed to the electrolyte. This will ensure a negligible potential drop throughout the electrolyte solution for low-current experiment. Various auxiliary electrodes are suitable for this cell including metal wire and metal foil electrodes as well as graphite rod. The bubbling of gas through the solution must be stopped prior to experiment.
