Abstract

The main trends in the development of analytical chemistry are the determination of increasingly lower concentrations of analytes in samples with complex matrix composition (trace analysis). While the obtained analytical results must be reliable, which means that they must accurately (truly and precisely) reflect the actual content of analytes in a representative sample of the material object under study. However, it is an extremely difficult and complicated task, which is a great challenge for analysts. Therefore, it is becoming increasingly important to pay attention to the problem of quality assurance and quality control (QA/QC) of the obtained results. This chapter provides information on QA/QC systems. The terms for quality of the results—its relevance and consequences, uncertainty estimation, traceability, measurement errors (types and effects)—are also described.

Keywords
