Staircase voltammetry with finite diffusion space
Electroanalysis, 1997AbstractA theory of the staircase voltammetry in a thin‐layer cell is developed. The influence of the cell thickness and the redox reaction rate constant on the current and the peak potentials is analyzed. For moderately thick cells, the kinetic maximum is predicted.

AbstractThe faradaic current of interest can often be obscured by some extraneous current. A new method called staircase pulse voltammetry (SPV), with which involving a potential pulse is superimposed on a staircase, is used for removing the double‐layer charging current This paper presents the theoretical consideration and the experimental evidence of

Theory of staircase voltammetry
Journal of Electroanalytical Chemistry (1959), 1965Abstract The theoretical relationships for voltammetry with a staircase potential function are developed for a reversible electrode reaction and are shown to be in accord with experiment. Current-potential curves are calculated and tabulated.

Abstract An equation is derived for the current in staircase voltammetry at any sampling time at a microdisk electrode for a reversible electrode reaction. On the basis of this equation, three differential staircase voltammetries are developed for the reversible case.

Low Frequency Sound for Effective Sensitivity Enhancement in Staircase Voltammetry
Analytical Letters, 2000ABSTRACT The success of improving the sensitivity in differential pulse anodic stripping voltammetry by exposure of low frequency sound has been reported in earlier papers. It has been found that audible sound in the low frequency range, of about 100 Hz or lower is very effective for this purpose, with an increase of the signal up to about 300 ...

Abstract A theory for staircase voltammetry (SCV) on randomly rough electrode is developed under reversible charge transfer conditions. An elegant general expression for the statistically averaged current that relates single potential step current transient to the multipotential step (staircase) current response is obtained using properties of ...
