Acquisition, Processing, and Presentation of 3-D Chromatovoltammographic Data Using an IBM PS/2and Par Model 273Potentiostat

Abdmc-A software package for interfacing an IBM P!3/2 and the EG&G PAR model 273 potentiostat/galvanostat is described. The software is capable of controlling the instrument and taking and displaying both potential and current data simultaneously as a function of time (chromatovokammetry). The software is written in both Microsoft QuickBASIC and QuickC for fast operatiou and easy portability. The sofiware can also be easily modified to provide user-friendly control of the PAR 273 potentiostat for a multitude of other computer-controlled electrochemical experiments. Ao application is described for the determination of catecholamines using high-performance liquid chromatography with a carbon fiber ultramicroelectrode and square wave voltammetry for detection.
