摘要
A new method to obtain the signal associated with a blank in differential pulse voltammetry and stripping voltammetry techniques is applied. The signal assigned to the blank is obtained by direct integration of the background noise extrapolated values of the base-peak width at different concentrations in order to obtain the zero concentration. Detection limits more amenable to a statistical evaluation are thus implemented, as recommended by the International Union of Pure and Applied Chemistry (IUPAC). (C) 2000 Elsevier Science B.V.
