Abstract

The quality of a laboratory’s most important product, information, can be assured through the proper use of statistical tools that support the quest for method accuracy and precision together with routine programs designed to assure their consistency over time. Methods for applying these tools are presented, along with examples and recommendations for routine applications. An additional topic, useful in assuring analytical accuracy, is the determination of sample sizes needed to detect crucial product defect and contamination levels.
