Knowledge-based system for the provision of an analytical strategy for simultaneous determination of metals by differential-pulse polarography

A knowledge-based system for differential-pulse polarography has been developed. This system allows to store all polarographic data (supporting electrolyte-metal-peak potential) and to process them in order to facilitate its handling, and provides the possibility to determine simultaneously in electrolytes or combinations of electrolytes a maximum number of metals with a minimum number of steps. Moreover the system is able to interpret the experimental data provided by a polarogram in order to identify the sample constituents. The systemʹ program is written in commercially available Q-PRO 4 and allows a very easy user communication. To use the system only a personal computer with MS DOS and a polarograph are required, which means that no extra investments are necessary.
