Square Wave Voltammetry

Create square wave method parameters.

Square wave Voltammetry (SWV) is in fact a special version of DPV.

DPV is SWV when the pulse time is equal to the interval / 2. The interval time is the inverse of the frequency (1 / frequency). Like DPV, the pulse amplitude is also normally in the range of 5 - 25 or 50 mV.

Methods:

• to_dict –

  Return the technique instance as a new key/value dictionary mapping.

• from_dict –
