Abstract. International comparisons in organic analysis (OA) are organized and coordinated by the Organic Analysis Working Group (OAWG) of the Consultative Committee for Amount of Substance (CCQM). OAWG also performs strategic planning and highlights the focus areas and challenges in OA. Realizing well that the amount of organic compounds and potential combinations of analyte-matrix is numerous, the OAWG has developed a systematic approach to the comparisons organizing. This approach allows to comprehensively describe the specifics of each comparison and appropriate features combination allows to cover all relevant aspects of OA. In terms of CMCs submission, recently the new concept has been created suggesting a broader view on the NMIs competence — it is the concept of “Broad Scope Claims” (BCs). BCs allow NMIs to submit CMCs for a wider range of analytes and matrices. In 2021 the OAWG has highlighted the priority areas for activities and promising methods and technologies for the OA for the period up to 2030.
In international comparisons on OA Russia is represented by VNIIM. Since 1998 VNIIM has been taking part in more than 35 comparisons covering various aspects of OA. Each successful comparison is a real and documented confirmation of Russia competence in the relevant OA area. At the moment 89 CMCs are presented in the Database, including 25 BCs.
Keywords: organic analysis, metrological traceability, international comparison, calibration and measurement capabilities, metrological service, standard sample.
