POLAC has been designed so that laboratory personnel, totally unfamiliar with computers and their languages, can write meaningful control and data acquisition programs after short familiarization. The POLAC system was originally used for spectrophotometric endpoint and kinetic analyses in the clinical laboratory. This system has also been applied to the automation of radioimmunoassay. Modular system design readily permits the incorporation of new measurement transducers, e.g. pH and other ion-selective electrodes, voltammetric electrodes, and fluorimeters. A specially built interface facilitates the control of external equipment. POLAC differs from most interpretive languages in that it first translates (assembles) the instructions into a compact binary representation. Program execution is an instruction-by-instruction interpretation of this representation.
