Abstract
A system to provide automatic, on-line notification of out-of-specification analytical results on process samples has been in service at ICPP for approximately eight years. Data from the analytical records system computer is used to statistically test the analytical results to determine whether they are within prespecified limits for the particular stream. If the results are outside the limit, the results are specifically flagged to Operations and a message is printed which will define the corrective action required.
