A rapid impedance-scanning electrochemical quartz crystal microbalance, Gamry’s eQCM 10M is a valuable analytical tool in the toolbox of anyone investigating interfacial processes. Interfacial processes that produce mass changes include corrosion, ion intercalation, ion adsorption, polymer growth and sensor binding events. These mass changes can be measured by monitoring the resonant frequencies of an oscillating quartz crystal.
A versatile instrument, the eQCM 10M accommodates any crystal from 1-10 MHz in any cell or holder. Its resolution allows detection in mass changes on the ng/cm2 scale, which is less than a monolayer of material.
