Thin-layer square wave voltammetry and square wave stripping voltammetry
Analytical Chemistry, 1987The feasibility of combining the highly sensitive techniques of square wave voltametry (SWV) and square wave stripping voltametry (SWSV) with a commercially available thin-layer electrochemical cell having a single-working electrode is demonstrated.

Fourier transform square-wave voltammetry
Journal of Electroanalytical Chemistry, 1994Abstract In this technique a potential excitation waveform is obtained by a superposition of a small amplitude square-wave modulation on a staircase function. The square-wave cycle is repeated several times (usually 16) at each potential step. The electrode response is sampled at even time intervals 2 n (where n = 2, 3, 4…) times per square-wave

Analysis of Cardamonin by Square Wave Voltammetry
Phytochemical Analysis, 2011ABSTRACTIntroductionSeveral biochemical studies have already shown that cardamonin has health promoting properties, such is in agreement with typical characteristics of chalcones. Although being a very promising compound for the nutraceutical field there is a lack of studies concerning its electroanalytical properties.ObjectiveTo develop an ...

Square-wave voltammetry for ECE mechanisms
The Journal of Physical Chemistry, 1990The theory of square-wave voltammetry is extended to include the ECE mechanism in which an intermediate chemical step occurs between sequential electrode reactions. Exemplary calculations show how the thermodynamic and kinetic parameters of this mechanism affect the shapes of square-wave voltammograms.

Theory of multiple square wave voltammetries
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1986Abstract A study of square wave voltammetries in which several pairs of opposing impulses are superimposed on each step of a staircase waveform, with or without integration of the current, is presented for reversible redox systems. The new fast techniques that result, yield responses greater than those obtained with the other classical methods.

Hot-SWV: Square Wave Voltammetry with Hot Microelectrodes
Analytical Chemistry, 2020A promising strategy to lowering detection limits in electrochemical analysis is the active modulation of the electrode temperature. Specifically, by tuning the electrode's surface temperature one can enhance detection limits due to improved electrode process kinetics and increased mass transfer rates, all without affecting the bulk solution. Motivated

Reverse scans in square wave voltammetry
Journal of Electroanalytical Chemistry, 2002Reverse scans in square wave voltammetry (SWV) leading to the regeneration of the substance initially present in solution are studied. Widths and peak potentials of waves in SWV performed with both negative and positive potential scans allow us to determine easily the kinetic parameters of a slow electrochemical reaction.

Square-wave voltammetry (SWV) is one of the four major voltammetric techniques provided by modern computer-controlled electroanalytical instruments, such as Autolab and µAutolab (both EcoChemie, Utrecht), BAS 100 A (Bioanalytical Systems) and PAR Model 384 B (Princeton Applied Research).
