Description
Summary:The measurement control program includes control of the analytical procedures, analyst training and qualification, and mass and balance control. A DEC 11/750 minicomputer and an interfaced Hewlett Packard 9836 desktop computer control these functions. The training and qualification program requires the analyst to analyze known and blind'' standards. Statistical tests for precision and bias are used to determine the analyst's qualification. An analyst must be qualified before he/she is permitted to use an analytical procedure for production samples. The qualified analyst must verify the operation of the measurement system prior to analyzing production samples. Balances must be tested and check-weighed and the analytical procedure must be verified by analyzing a blind'' standard. The data from the analysis is entered to the laboratory computer where it is determined to pass'' or fail.'' The analyst is notified immediately by the laboratory computer if the standard, chemical or mass, has passed. The results of the chemical standard are transferred to a Hewlett Packard computer where the data are evaluated routinely. The evaluation determines the bias and the uncertainty of each analytical procedure as used by the analysts. These parameters are applied to the sample results to bias correct the results and calculate the measurement uncertainty. 1 ref., 2 figs.
