OCV

Open Circuit Voltage (OCV) is the same as Open Circuit Potential (OCP). This is the potential where no current is flowing, because the circuit is open.

OCP with MUX8-R2

The multiplexer MUX8-R2 offers the possibility to record reliable Open Circuit Potential (OCP) measurements in the Alternating mode, which allows to monitor the OCP of multiple samples / working electrodes over time with a single potentiostat. This is a significant improvement compared to its predecessors MUX8 and MUX16. In this application note it is demonstrated how to setup and perform an OCP measurement with the MUX8-R2 in the Alternating mode.
