A low-cost digital acquisition unit for a CARY-210 spectrophotometer has been designed and constructed. The data-flow is controlled by a 6809 microprocessor driving four parallel interface adapters. Two RS232-C serial links are provided for communication with a terminal and a mass storage unit. The acquired data are processed by a personal computer. Included are several software modules, based on powerful signal-processing algorithms, which are highly useful in kinetic studies.

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.
