Electrochemical analysis Quartz micro-balance (EQCM)

1Mhz to 20Mhz EQCM


The QCM922 microbalance has been developed for piezoelectric gravimetry for masses ranging from nano-gram to microgram.


  • Measurement of mass changes in mono-layers

It allows to follow the frequencies and the resistances of resonance of a quartz crystal covered with a layer of platinum or gold. The resonance frequency changes with the effective mass at the surface of the crystal and the resonance resistance varies as a function of the viscosity of the element reacting with the surface of the crystal. This micro-balance can be used for a very wide range of applications including EQCM with potentiostat / galvanostat.
