Current Interrupt module 10A

Product description

The Current Interrupt Module (CIM) iis a module for measuring the IR-drop via the current-interrupt technique. This device is integrated in a cell-cable compliant with the potentiostat.

  • Current compliance: ±10A
  • Voltage compliance: ±10V
  • Interrupt time: < 2µs

 

Functionality

Enable the current interrupt technique for measuring the IR-drop of the electrochemical system.

Installation

The male side of the CIM can be placed directly on the cell connector of the IviumStat/CompactStat. The cell cable can be connected to the female side, as before. The CIM is thus connected between the instrument and the cell cable. When not using the current interrupt technique all signals are passed through this module and it is fully compatible with the situation without CIM. However, the CIM adds ca. 130 mOhm impedance to the cell cable. This should be taken into account when measuring in the 2-electrode mode and it will slightly lower the compliance voltage of the potentiostat. The latter will only have a significant effect when measuring very low impedance objects.

Application

The CIM can be used for measuring the IR-drop of an electrochemical system via the current interrupt technique. As the name of the technique suggests, the current of a running experiment is interrupted instantly and the response of the cell potential is measured in high speed mode. The momentary drop of the cell potential, representing the IR-drop of the electrochemical system, is then shown in a graph of the potential vs. time
