Quartz crystal microbalance

QCM200

QCM (Quartz Crystal Microbalance) is based on the piezoelectric effect principle of quartz crystals. By detecting the change in output frequency, it calculates the mass of substances attached to the surface of QCM crystals with high sensitivity. Suitable for various occasions such as electroplating/corrosion, electrode modification, as well as studying solid-liquid interfaces, interface rheology, and biomolecule interactions.
