The Analytical Control as an Integral Part of Material Diagnostics

Abstract

Analytical control is an applied subdiscipline of analytical chemistry that involves representative sampling, identification of the chemical (elemental, phase, molecular, isotopic, etc.) composition, metrological characterization of the obtained results, and statement of conformity of the objects under analysis to the imposed requirements. The article provides a description of the above basic components of analytical control alongside important aspects such as unification and standardization and accreditation of analytical laboratories. Special attention is paid to the methodology as the basic component of analytical control, its metrological characteristics, and metrological support of the analysis.
