[Elektronische Daten] [Manuel Alvarez-Prieto, Juan Jiménez-Chacón] A classification in categories according to the intended use of results in analytical chemistry is presented. A comprehension of the metrological requirements of these categories allows to properly understand important topics such as quality of analytical results, fitness for purpose, implication of systematic errors, needed levels of measurement uncertainty, traceability requirements and some other issues. Implications on fundamental concepts and important activities in analytical chemistry, such as quality control practices, validation of analytical procedures, use of replication programs, participation in interlaboratory studies and some other activities, are discussed. The different categories are intended to state compliance with specification limits, to define the monetary value of a material or the amount of substance, the mass or the volume of a chemical species, to know the composition of a material without quantitative requirements and some others related to interlaboratory and intralaboratory studies. Some of these categories include subcategories within them. The roles of sampling and qualitative tests (identification of chemical species and sampling screening methods) in the classification are discussed.
