Computer-Aided Flow-Analysis for Laboratory Use and Process Analysis

Abstract

Flow-based methods of analysis such as flow-injection analysis and sequential-injection analysis are being used increasingly in the automation of laboratory methods and for process analysis. Full exploitation of these techniques in automated modes of operation necessitates computer control and data acquisition. Although most commercial systems are microprocessor driven, flexibility is seldom built into the software, thereby severely limiting the ingenuity of the analysts in the use of these instruments in novel and imaginative applications. A software package is described which allows for easy automation of flow-based analysis systems. The emphasis in the design of this package has been on flexibility, with numerous user-selected options and a wide variety of features. Applications to laboratory and plant analysers are described.
