This AfterMath software module includes support for dual electrode and other popular electroanalytical techniques on the Pine WaveDriver 20 bipotentiostat/galvanostat system. A list of all supported methods is provided below.

### Galvanostatic Methods

• Chronopotentiometry (CP), also known as Constant Current Electrolysis
• Staircase Potentiometry (SCP), including Cyclic Staircase Potentiometry (CSCP)

### Cyclic Step (Charge/Discharge) Methods

• Cyclic Step Chronoamperometry (CSCA), capable of charge/discharge under potentiostatic control
• Cyclic Step Chronopotentiometry (CSCP), capable of charge/discharge under galvanostatic control

### Dual Working Electrode Methods

• Dual Electrode Bulk Electrolysis (DEBE), controlled potential, controlled current, or open circuit potential
• Dual Electrode Cyclic Voltammetry (DECV), includes collection, shielding, window, and diametric variants

### Hydrodynamic Methods

Note: Control of the rotation rate by the potentiostat requires a special cable (click here for details).

• Rotating Ring-Disk Voltammetry (RRDE), includes collection, shielding, window, and diametric variants
• Koutecky-Levich RDE Series (KL-RDE), acquires series of rotating disk voltammograms at various rotation rates
