New module: EQCM
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.
	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 ● PGSTAT compatibility PGSTAT128N, PGSTAT302N and series 7 Autolab instruments type PGSTAT12 and PGSTAT30
