Determination of ascorbic acid by differential pulse voltammetry
Fresenius' Zeitschrift für analytische Chemie, 1982 A new approach to the determination of ascorbic acid has been realized with differential pulse voltammetry (DPV) on the carbon paste electrode (CPE). The problems of the reproducibility of the surface of this electrode have been resolved by using always ...

Paired pulse voltammetry for differentiating complex analytes [PDF]
The Analyst, 2012 Although fast-scan cyclic voltammetry (FSCV) has contributed to important advances in neuroscience research, the technique is encumbered by significant analytical challenges. Confounding factors such as pH change and transient effects at the microelectrode surface make it difficult to discern the analytes represented by complex voltammograms.

The Simulation of Differential Pulse Voltammetry
Electroanalysis, 2001 The differential pulse voltammetry (DPV) experiment has been simulated using the backwards implicit finite difference approach. Results are reported for the general case of a one-electron redox transfer process at a planar electrode in stationary solution with a semiinfinite diffusion layer and are in excellent agreement with those predicted by an ...
