An instrumentation-orientated micro-computer: an extremely inexpensive data acquisition computer optimised for the automated laboratory

Abstract

The design and realisation of a maximally versatile multi-access on-line digital computer system for support of instrumentation design, experiment control and data interpretation in chemical research are discussed. Features included are (i) development of low-cost modular experiment control processors for installation in, and dedication to, laboratory-captive instrumentation systems, (ii) configuration and installation of a central multi-programmed computer system which serves as a common experiment-design, data analysis and mass-storage resource, (iii) current and proposed research of new varieties of computer-assisted experiment design techniques for the rapid implementation of instrumentation by research chemists and (iv) application of the complete system to a variety of chemical research environments representative of a broad range of instrumentation requirements. The modular experiment control processors (micro-computers) serve as remote, “intelligent” data acquisition terminals of the central system. Their design utilises recent developments in micro-circuit technology and the results of detailed analysis of the requirements of the research environment to achieve a unique level of cost-effectiveness.
