Multi-channel potentiostat with adjustable auxiliary electrode potential

摘要

The potentiostat (1) has a reference terminal (2), a counter-electrode terminal (3), and working terminals (4, 5) respectively connected to a reference electrode (REF), a counter-electrode (CE) and working electrodes (T1, T2) of an electrochemical cell. A control circuit controls counter-electrode voltage (VCE) applied to the counter-electrode terminal, and has an input terminal connected to a predefined potential (VP) i.e. voltage supply unit, and another input terminal to which regulating voltage (VTX) representing one of the voltages (VT1, VT2) of the working terminals is applied.
