In the ‘Vocabulaire International de Métrologie’ (VIM) as published by the ‘Bureau International des Poids et Mésures’ (BIPM) the term ‘metrology’ is defined as “the science of measurement and its application” and covers all theoretical and practical aspects of any measurement, including uncertainty and field of application. This book chapter on metrology summarizes the basic metrological terminology related to inorganic sector field mass spectrometry. General terminology and explanatory notes on terms related to e.g. validation, uncertainty and calibration is given, where VIM-based terminology is compared to and supplemented by IUPAC-based definitions and recommendations. A compact overview about the most relevant metrological institutions worldwide is given in order to provide insight into the organization of metrological network institutions. Metrological traceability, which is required for the establishment of a calibration hierarchy, providing that all input parameters into a model equation are traceable to a common reference (e.g. the SI-unit) is defined together with related aspects such as the use of reference materials. The principle of the estimation of a sound measurement uncertainty is presented. This book chapter should contribute to the mutual understanding of metrological terminology being used within the scientific community.
