Abstract : Instrumentation and methods are presented for determining the Faradaic and capacitive responses of an analytic over a wide range of experimental conditions. Experiments were carried out by a fractional factorial design so that the best experimental conditions or changes in conditions for analytic identification could be determined in a later pattern recognition analysis. Percent ethanol, pH, surfactant concentration, number of cycles, scan rate, and mercury drop hang time all produced changes in cyclic differential capacity curves and cyclic staircase voltammograms which were unique and reproducible. Capacitive and Faradaic responses were determined independently for 19 nitrocompounds under most experimental conditions. (Author)
