Compliance Voltage: How Much is Enough?
1 February 2017
The compliance voltage of a potentiostat is the maximum voltage that the potentiostat can apply to the counter electrode in order to control the desired voltage in the electrochemical cell. When purchasing a potentiostat, you need to choose one with a high enough compliance voltage for your electrochemical cell, however the higher compliance value the higher the cost. This application note describes how to calculate how much compliance voltage you need for your electrochemical cell.
