Voltammetry of porous layers: Staircase vs analog voltammetry [PDF]
Journal of Electroanalytical Chemistry, 2016 Abstract The use of staircase ramps for cyclic voltammetry rather than true linear analog ramps can lead to significant misinterpretation of the signals recorded for the measurement of diffusional redox species with either reversible or irreversible electrode kinetics measured at electrodes modified with porous layers.

CONSIDERAÇÕES TÉCNICAS QUANTO AO USO DA VOLTAMETRIA DE VARREDURA ESCALONADA EM PROCESSOS ADSORTIVOS
Química Nova, 2015 Cyclic voltammetry has become one of the most useful tools in modern electrochemistry, but the use of digital potentiostats should be treated with caution by users. Staircase Voltammetry utilizes some parameters to build up the potential ramp.

Influence of Potentiostat Hardware on Electrochemical Measurements [PDF]
SensorsWe describe two operating modes for the same potentiostat, where the redox processes of hydroquinone in a hydrochloric acid medium are contrasted for cyclic voltammetry (CV) as functions of a digital/staircase scan and an analogue/linear scan.

New complex dimensionless variable in cyclic staircase voltammetry on the rotating disk electrode
Journal of Electrochemical Science and Engineering, 2021 Cyclic staircase voltammograms of a simple, reversible oxidation on the rotating disk electrode is analysed by the digital simulation. It is demonstrated that the peak currents and potentials depend on the single dimensionless variable that considers ...
