Fast Cyclic Voltammetry
This page documents the Fast Cyclic Voltammetry (FCV) method.
pypalmsens.FastCyclicVoltammetry
Create fast cyclic voltammetry method parameters.
In Cyclic Voltammetry a cyclic potential scan is performed between two vertex potentials
vertex1_potential and vertex2_potential.
The scan can start (begin_potential) at one of these vertex potentials or anywhere in between.
A CV becomes a Fast CV if the scan rate in combination with step_potential results in a rate of over 2500
points / second (scan_rate / step_potential > 2500).
