eQQCM 10M Quartz Crystal Microbalance

Gamry’s eQCM 10M is a rapid, impedance-scanning electrochemical quartz crystal microbalance (EQCM). The EQCM adds a valuable tool in the analytical toolbox of anyone

Product Category: Potentiostats, Quartz Crystal Microbalance

Industry: Electrochemistry, Life Sciences

Supplier: Gamry


The eQCM 10M is a versatile quartz crystal microbalance that accommodates any crystal from 1-10 MHz in any cell or holder.  Its resolution allows you to detect mass changes on the ng/cm2 scale. This is less than a monolayer of material!  Our system comes with everything you need to get started – the eQCM 10M, Teflon® cell, 10 MHz Au-coated crystals (5x), cables, manuals, and software.


  • Any crystal from 1-10 MHz in any cell
  • Detect ng/cm2
  • USB Interface
  • Integrated QCM and Gamry Potentiostat acquisition
  • Impedance scanning gives both ƒs and ƒp, the series and parallel resonant frequencies
  • Data Analysis in Gamry’s flexible and customizable Echem Analyst™


  • Electroactive Polymers
  • Li+ Intercalation
  • Corrosion Studies
  • Electrodeposition
  • Self-Assembled Monolayers
  • Antibody-Antigen Interactions
  • Surfactant Adsorption
  • Protein Adsorption
  • Ion and Solvent Transport

The eQCM 10M rapidly scans a frequency window around the two resonant frequencies (these resonant frequencies are explained in our Basics of an eQCM App Note).  The advantage of scanning through the two resonant frequencies is that you no longer need to cancel the parasitic capacitance in order to maintain oscillation.  Additionally, the relative impedance spectrum is displayed each time a data point is acquired, giving you insight into bubble formation on your electrode or improper cell setup.  Having the two resonant frequencies also allows you to do basic dissipation monitoring.  When ƒs and ƒp respond similarly your film is rigid, however, when ƒs and ƒp respond differently the film is not rigid.

Resonator also allows you to adjust the driving amplitude of the crystal.  This is especially important when working in an ionic liquid (IL) or a viscous solution where damping is especially high. The ability to manually increase the driving amplitude for heavily-loaded crystals offers a significant advantage over straight dissipation or time-resolved techniques.

Data analysis is done in our flexible and customizable Echem Analyst™.  We give you a variety of plotting options to allow you to display the data as you want.  You can plot straight mass change versus time, mass versus charge, mass versus potential, or a basic form of dissipation versus time.
