Minicomputer controlled, background subtracted anodic stripping voltammetry: Evaluation of parameters and performance

A new minicomputer controlled anodic stripping voltammetry technique is described. The technique uses differential voltammetry on one electrode and uses a rapid data averaging algorithm to avoid the need for scan averaging, allowing excellent sensitivities and short analysis times, with adequate reproducibilities. Both linear scan and staircase waveforms are discussed and the approximate Roe-Toni theory for linear scan voltammetry is shown to apply. The viability of the technique in solutions showing a large background is also discussed.
