A study on a multi-order semi-differential oscillographic chronopotentiometric instrument

By applying a convolution technique to the processing of oscillographic chr onopotentiometric signals, a new electroanalytical method, multi-order semi differential oscillographic chronopotentiometry, is presented, and a correl ative instrument has been designed. The instrument can generate alternating current with sine, triangle, and square waveforms from an internal signal source, and also can be inputted other kinds of alternating current from an outside signal source. It has the capability of potential drop compensatio n and electrode (normal or micro working electrode) cleanup. By using the i nstrument, not only dE/dt-t, Y-2-t, Y-3-t, Y(0.5-)t, Y-1.5-t, Y-2.5-t, and Y-3.5-t signals, but also the oscillographic signals synthesized by the afo rementioned signals with E-t signal can be obtained.
