Модель МБ была адаптирована для ВПП, и затем был разработан оптимизированный алгоритм определения чистоты данных компонентов. На примере бензола продемонстрирована работоспособность и эффективность предложенного подхода, который включал в себя модель МБ и алгоритм исследований. Подход успешно реализован на государственном первичном эталоне ГЭТ 208: с помощью алгоритма воспроизведены единицы массовой доли основного компонента в бензоле, толуоле, н-гептане, изооктане, н-додекане, н-гексадекане, пропанол-1, пропанол-2, н-октаноле. Аттестованные чистые вещества использованы для создания стандартных образцов утвержденного типа (ГСО) состава соответствующих органических соединений. Предложенный подход может быть применен в дальнейшем для оперативного расширения номенклатуры СО состава органических компонентов.</p></abstract><trans-abstract xml:lang="en"><p>The article discusses the features of using the mass balance (MB) method widely used in the Russian Federation to determine the purity of a selected group of organic components – such substances, and the MB model was adapted for substances suitable for separation or purification by distillation. Then an optimized algorithm for determining the purity of these components was developed. The operability and efficiency of the proposed approach is demonstrated on the example of benzene. The approach included the MB model and research algorithm. It has been successfully implemented on the State Primary Standard GET 208; the units of the mass fraction of the main component in benzene, toluene, n-heptane, isooctane, n-dodecane, n-hexadecane, propane‑1, propane‑2, n-octanol are reproduced using the algorithm. Certified pure substances were used to create certified reference materials (CRMs) for the composition of the corresponding organic compounds. The proposed approach can be applied in the future for the rapid expansion of the list of GSOs for the composition of organic components</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вещества</kwd><kwd>пригодные к очистке и выделению методом перегонки</kwd><kwd>чистые органические вещества</kwd><kwd>массовая доля основного компонента</kwd><kwd>метод массового баланса</kwd><kwd>метрологическая прослеживаемость</kwd><kwd>примесные компоненты</kwd><kwd>бюджет неопределенности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>substances suitable for separation or purification by distillation</kwd><kwd>pure organic substances</kwd><kwd>mass fraction of the main component</kwd><kwd>mass balance method</kwd><kwd>metrological traceability</kwd><kwd>impurity components</kwd><kwd>uncertainty budget</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">Стратегия Консультативного комитета по количеству вещества ((The Consultative Committee on Amount of Substance; CCQM) при Международном бюро мер и весов (International Bureau of Weights and Measures; BIPM) [сайт] URL: https://www.bipm.org/en/committees/cc/ccqm/strategy.html</mixed-citation><mixed-citation xml:lang="en">The Consultative Committee on Amount of Substance; CCQM International Bureau of Weights and Measures; BIPM.
