“…Computer Interface. A computer-controlled ramp generator was constructed (similar to Thomas (20)) capable of producing a linear ramp up to ±38 V/s. The slope of the ramp is set by the digital-to-analog converter (DAC) voltage, and the ramp is started or stopped by a digital control bit from the computer.…”

Computerized pattern recognition was used (or discriminating between complicated and uncomplicated electrode processes and for Identifying the mechanism of the electrode process using the shape Information contained In the data from a single voltammetric experiment. Features based on the Fourier transform, which were selected to give the best classification accuracy with theoretical cyclic linear sweep voltammetry (CLSV) data, could be used to classify experimental CLSV or cyclic staircase voltammetry (CSCV) data. The theoretical data were classified with an accuracy of 97%. The experimental data were correctly classified 93% of the time when the shape of the voltammogram was determined by a single mechanism which was Included In the theoretical training set.

Cybernetic analytical voltammetry offers a powerful approach to efficient management of various methods of quantitation when using transient techniques such as differential pulse polarography and stripping voltammetry. In this work a microcomputer system has been developed with capabilities of assigning the reliability of analytical determinations based upon direct calibration from multitime domain experiments. The system Incorporates peak height, peak width, and potential measurements as a function of time and concentration to construct a comprehensive data base as a reference. Unknown solutions are compared against this extensive data base to detect If Interference Is present and ultimately to decide whether the direct calibration method Is appropriate or the more time-consuming method of standard addition must be employed. Examples considered Include the determination of steroids by differential pulse polarography or cathodic stripping voltammetry and cadmium or lead by similar techniques.
