Acquiring of the experimental data from PA-3 polarographic analyser and their treatment by personal computer was performed using commercially available AD/DA converter and a software developed on basic of Visual Basic 3.0 developing environment. Only minimal hardware arrangements to PA-3 are necessary when requiring no special technical skill. Analyser's output to XY recorder is connected to the input of AD/DA converter and digitised data are transferred to the computer using its serial port. Further processing of the data is handled by software "Polarograf" whif is able to acquire, plot and manage experimental data and capable of exporting them in a readable form for Excel or other software. Functionality of the system was verified using several model voltammetric systems measured with carbon paste electrodes. The same principle of interfacing can be applied with only small changes practically to all analogue electroanalytical instrumentation.
