Electrochemical quartz crystal microbalance (EQCM) is a method to determine a mass change related to electrode reactions by measuring a change in the resonance frequency of the quartz. Because the EQCM can detect a nano-scale mass change, it is a powerful tool for analysis of electrode reactions. This article provides an introduction of the EQCM principle, applications of the EQCM to corrosion studies, and problems for measurements.
