EQCM - Electrochemical Quartz Crystal Microbalance

The EQCM module provides the means to perform Electrochemical Quartz Crystal Microbalance experiments. The EQCM module measures a mass change per unit area by recording the change in resonant frequency of a quartz crystal oscillator.

Measurements in the sub μg/cm2 are possible. The EQCM can be fitted with 6 MHz, AT-cut crystals. An application note is available: EQCM study of underpotentially deposited (UPD) lead adlayer on gold.

The module comes with a dedicated electrochemical cell and is supported in NOVA only. The specifications are:

  • Oscillation frequency 6 MHz
  • Resolution 0.07 Hz
  • Relative accuracy 1 Hz
  • Sampling rate 50 S/s
  • Available frequency range 80.000 Hz
