Traceability in organic analysis. Report 1: Equivalence of the national and international measurement standards

Abstract

The issues of the functioning of the BIPM and the corresponding committee -CCQM, coordinating the work on the comparisons of national standards in the field of organic analysis have considered in this article. The structure and tasks of the CCQM have described and the measurement categories for the amount of substance have given. The main aspects of the OAWG activities have discussed and the issues of systematization and separation of comparisons in the field of organic analysis have discussed in detail and various approaches to the development of competence areas based on key comparisons have set out. The fundamental importance of pure organic substances in providing metrological traceability in organic analysis has highlighted. The key role of the State Primary Standard GET 208 in terms of confirming the equivalence of the calibration and measurement capabilities (CMC) of Russia at the international level has been determined.

Development of International Key Comparisons in the Field of Chemico-Analytical Measurements

“…Over the period from 1998 to the present, the Russian Federation has taken part in more than 35 international comparisons organized by the CCQM BIPM, which cover the most different aspects of organic analysis, including the determination of the purity of organic substances belonging to different chemical groups (aldrin, L-valine, folic acid, bisphenol A, dimethyl sulfone) [ 13 ]. Information on the approved calibration and measuring capabilities (CMC) based on the results of comparisons is publicly available on the official website of the BIPM.…”
