Abstract

The attainment of reliable accuracy and precision in chemical analyses at trace and ultratrace levels is difficult but can be obtained by implementation of a good quality assurance program and by designing and controlling the total analytical measurement process. Quality assurance, the steps in the total analytical measurement process, the impact of these steps on the determination of chemical species, and two case studies, which illustrate many of the requisite procedures to obtain reliable data, are discussed.
