Complementary techniques are often necessary when investigating surface phenomena. Electrochemistry is ideally suited to be paired with Quartz Crystal Microbalance with Dissipation (together EQCM-D) since both are surface techniques.
QCM-D can provide real-time information on mass and structure of thin films in the form of changes in frequency or dissipation, while electrochemistry can be the stimulus of an interaction or provide information about interfacial charge transfer.
A typical EQCM-D combination is cyclic voltammetry (CV) and QCM-D, where simultaneous measurements of the frequency (f), dissipation (D), and current (I) are made as they respond to a varying potential (E) above one single sensor surface. This allows for direct correlation between QCM-D and electrochemistry results. In these examples the Q-Sense electrochemistry module QEC 401 was used where the standard sensor acts as both the QCM-D sensor and as the working electrode of the electrochemistry cell.

Q-Sense offer a optional Electrochemistry Module, that allows simultaneous QCM-D electrochemistry or QCM-D / EIS measurements. The design enables flow measurements, which is important for well controlled experiments. Also, the module will withstand the harsh conditions necessary for some electrochemistry applications.
