ECI10M - Electrochemical impedance spectroscopy measurements up to 10 MHz

With the ECI10M, the maximum frequency that can be reached during electrochemical impedance spectroscopy measurements is extended up to 10 MHz.

The ECI10M consists of a module, installed in the Autolab potentiostat/galvanostat and coupled to the FRA32M module and an external interface designed to be placed in close proximity of the electrochemical cell in order to minimize the effects from the electrode cables. The small form factor of the external interface allows measurements in a glove box or Faraday cage.

The ECI10M uses the Automatic Amplitude Correction algorithm (AAC) provided in the NOVA software to ensure that the amplitude applied on the cell corresponds to the required amplitude at all times, thus maximizing the resolution while respecting the linearity and stability conditions during the measurement.

The ECI10M is available for the Autolab PGSTAT302N and the Autolab PGSTAT128N. A FRA32M module is required for electrochemical impedance spectroscopy measurements.
