A Sinclair ZX81 microcomputer was interfaced with the telemetry output of a Technicon Auto Analyzer II colorimeter using an inexpensive analog interface, A computer program was written in BASIC to monitor the flow of samples within the Auto Analyzer system, measure peak heights, and calculate concentrations. Missing peaks are detected. The system provided totally automatic low-cost (under $500) data acquisition and handling. Data acquisition and computations by the microcomputer were consistently as reliable as those performed by laboratory personnel. The potential for greater accuracy was believed to exist.
