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.
Advantages
- Measurement of mass changes in mono-layers
Description
Specification
Applications
Resources
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.
