Implementation and Automation of Analytical Statistical Process Control

Source

The goal of analytical statistical process control (ASPC) is to reduce process variability, which in turn will improve the quality of our products. In the case of laboratories, the products are analyses. The analyses, in turn, are used for process control and to verify that products meet customer specifications.

ASPC is implemented through use of control charts, which require a modest understanding of statistics. This paper briefly describes the practical side of developing and interpreting control charts. It also includes a discussion on what is needed to automatically maintain and interpret control charts for use with multi-element analyzers, such as optical emission (OE), X-ray fluoresence (XRF), and plasma spectrometers.
