High frequency impedance spectroscopy

High frequency impedance spectroscopy
Order number: ECI10M

The ECI10M extends the measurable range for electrochemical impedance spectroscopy to a maximum of 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) 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.
