Information concerning these samples, the 60 people handling the samples, and the 90 methods of running samples is registered, processed, and accessed daily. A manual paper system was found to be inadequate for an efficient, accurate, interacting network; thus, the need for a more spontaneous system emanated. The Analytical Laboratory Computer System is designed to automate and streamline the generation and storage of this data and to increase the credibility of sample results. A 256 K byte Data General Eclipse C/300, a 62 K byte Hewlett-Packard 9845A, and 8 Tetronix 4023 terminals are being used to achieve this goal. The Eclipse is used for data input-output and the calculation and bias correction of laboratory results; the 9845 computer is used for data manipulation for quality control. Utilization of the data provides some powerful tools in such areas as quality control, data classification, and analyst/method performance evaluation. The simplicity and clarity of operating the system as well as the complexities of design and implementation are also discussed
