Представлены решения актуальных задач, реализуемые, в том числе, в процессе новых международных сличений под эгидой Консультативного комитета по количеству вещества – Консультативного комитета по метрологии в химии и биологии Международного комитета мер и весов. Описаны вопросы и задачи развития ключевых сличений в следующих областях: изотопные измерения; определение чистоты веществ; органический анализ; биоаналитические измерения; измерения параметров аэрозольных частиц; газовые и электрохимические измерения. Показано, что участие в международных ключевых сличениях позволяет получать надёжные и достоверные результаты измерений показателей состава и свойств газовых и жидких сред, а также твёрдых веществ и материалов.</p></abstract><trans-abstract xml:lang="en"><p>The most challenging goals in the field of chemico- and bioanalytical measurements are described. Solutions of these problems are presented, which are being solved in particular by participating in new international comparisons organized by the Cosultative Committee on the Amount of Substance of the International Committee on Weights and Measures (CCQM CIPM). The purposes and tasks of developing key comparisons in the following areas are described: isotopic measurements; determination of the purity of substances; organic analysis; bioanalytical measurements; measurements of aerosol particle parameters; measurements in the field of gas analysis and electrochemistry. It is shown that participation in international key comparisons makes it possible to obtain valid and reliable results of measurements of the composition and properties of gas and liquid media, as well as solid substances and materials.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сличения</kwd><kwd>количество вещества</kwd><kwd>моль</kwd><kwd>отношение изотопов</kwd><kwd>прослеживаемость</kwd><kwd>примеси</kwd><kwd>чистые вещества</kwd><kwd>биомаркеры</kwd><kwd>счётная концентрация частиц</kwd><kwd>массовая концентрация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>comparisons</kwd><kwd>amount of substance</kwd><kwd>mole</kwd><kwd>isotope ratio</kwd><kwd>traceability</kwd><kwd>impurities</kwd><kwd>pure substances</kwd><kwd>biomarkers</kwd><kwd>counting concentration of particles</kwd><kwd>mass concentration</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">General Conference for Weights and Measures (CGPM), Resolution 1 of 26 meeting of CGPM (13–16 November 2018), available at: https://www.bipm.org/en/committees/cg/cgpm/26-2018/ resolution-1 (ac cessed: 23.06.21).</mixed-citation><mixed-citation xml:lang="en">General Conference for Weights and Measures (CGPM), Resolution 1 of 26 meeting of CGPM (13–16 November 2018), available at: https://www.bipm.org/en/committees/cg/cgpm/26-2018/resolution-1 (accessed: 23.06.21).</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Marquardt R., Meija J., Mester Z., et al, Defi nition of the mole (IUPAC Recommendation 2017), Pure Appl.
