GRAPHICAL ABSTRACT

ABSTRACT

This article presents some typical questions from practitioners, trying to implement metrological concepts in their everyday chemical analysis work, and answers to them by the authors, in the context of the authors’ pragmatic view on applying the metrological principles to chemical analysis. Several of the presented questions are staples at training seminars and during on-line courses. The answers to the questions reflect the authors’ opinions and are not always fully in line with the generally accepted positions.
