Electrochemical quartz crystal microbalance

ID: electrochemical-quartz-crystal-microbalance

The Electrochemical Quartz Crystal Microbalance (EQCM) is a sensitive analytical technique that combines electrochemical and quartz crystal microbalance (QCM) methods to study mass changes and interfacial phenomena at the nanoscale. It is based on the principles of piezoelectricity, where a quartz crystal oscillates at a specific frequency. When mass is deposited or removed from the crystal surface, it alters the frequency of oscillation, which can be measured very precisely.
