The

existence of integrated electronic circuits has changed radically our thinking with respect to performing chemical analyses. L o w cost microprocessors are now integral parts of commercial analytical instrumentation. Minicomputers have the ability to control experiments, to collect data, and to perform calculations with ever increasing facility. Thus, there is considerable interest on the part of the chemical analyst to use computational techniques to validate the measurement process. Chapters 1 and 2 describe the importance of establishing statistical control of the measurement process and emphasize the use of graphical techniques which can be implemented conveniently on digital computers. After control of the measurement process has been established, it is necessary to evaluate systematic errors; Chapters 3 and 4 are devoted to this subject. Chapter 5 describes an innovative procedure which uses a laboratory minicomputer to optimize the variables i n a chemical analysis. Chapter 6 outlines some examples for evaluating statistical control i n testing laboratories. I would like to thank the authors for their diligent effort and to express appreciation to Carol Shipley and the text editing staffs of the Analytical Chemistry Division and the Institute for Materials Research, N B S , for helping with the manuscripts.
