Systeme d'analyse et d'acquisition de donnees cinetiques pilote par microprocesseur

This paper describes a low-cost 6809 microprocessor-based system designed for the acquisition, analysis, preprocessing and recording of electrochemical kinetic data. Determination of second-order rate constants involves a preliminary calculation of a characteristic parameter of the electro-chemical system investigated, the value of which, computed and displayed by our apparatus, allows checking of the correctness of the experimental conditions. At the end of the experiment the data are recorded on a magnetic tape cartridge and can be transferred from the tape to a minicomputer for further mathematical processing.
