Galvanostatic vs. potentiostatic mode
When to choose potentiostatic mode:
- When studying redox reactions, corrosion, electroplating, or any process where maintaining a constant potential is crucial.
- When performing cyclic voltammetry or other techniques that involve sweeping the potential across a range of values.
- When investigating electrochemical behavior, kinetics, and electrode surface properties.
Application note: Potentiostatic intermittent titration technique (PITT)
Application note: ASTM G5 – Potentiodynamic Anodic Polarization Measurements
Application note: Cyclic Potentiodynamic Polarization Measurements as per ASTM G61
When to choose galvanostatic mode:
- When studying electrolysis, electrodeposition, or any process where maintaining a constant current is critical.
- When performing experiments involving fuel cells, batteries, or any electrochemical cell that requires a specific current input.
- When using electrochemical impedance spectroscopy or other techniques that analyze the electrical response of a system.
