Таким образом были расширены функциональные возможности ГПЭ в соответствии с актуальными требованиями отечественной промышленности и в целях успешного участия России в международных сличениях в области органического анализа в среднесрочной перспективе.</p><p>В статье представлены материалы по исследованию возможностей новой установки для решения измерительных задач в области органического анализа, описаны конкретные аналитические техники и методы измерений, приведены экспериментальные данные и обобщенные результаты. На основании выполненных исследований улучшены метрологические характеристики ГЭТ 208 в части воспроизведения единиц массовой (молярной) доли основного компонента в чистых органических веществах, массовой доли органических компонентов в растворах и материалах.</p><p>Совершенствование ГЭТ 208 позволило создать научный, методический и приборный задел для воспроизведения единиц величин широкой номенклатуры органических соединений.</p></abstract><trans-abstract xml:lang="en"><p>In the context of the rapid development of the Russian pharmaceutical industry, there is an urgent need to improve the State Primary Standard for the units of mass (molar) fraction and mass (molar) concentration of organic components in liquid and solid substances and materials based on liquid and gas chromatography-mass spectrometry with isotope dilution and gravimetry (GET 208).</p><p>As a result of the improvement of GET 208 carried out in 2023, a new installation based on the highperformance liquid chromatography/high-resolution mass spectrometry method was included in the standard. Thus, the functionality of the GPE was expanded in accordance with the current requirements of the domestic industry and for the purpose of Russia’s successful participation in international comparisons in the field of organic analysis now and in the medium term.</p><p>The article presents materials on the study of the capabilities of the new installation for solving various measurement problems in the field of organic analysis, describes specific analytical techniques and measurement methods, and provides experimental data and summarized results. Based on the completed studies, the metrological characteristics of GET 208 have been improved in terms of reproducing units of mass (molar) fraction of the main component in pure organic substances, mass fraction of organic components in solutions and materials.</p><p>Improvement of GET 208 made it possible to create a scientific, methodological and instrumental basis for reproducing measurement units for a wide range of organic compounds.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Государственный первичный эталон</kwd><kwd>органический анализ</kwd><kwd>метод массового баланса</kwd><kwd>масс-спектрометрия высокого разрешения</kwd><kwd>чистые органические вещества</kwd><kwd>активные фармацевтические субстанции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>State Primary Standard</kwd><kwd>organic analysis</kwd><kwd>mass balance method</kwd><kwd>high-resolution mass spectrometry</kwd><kwd>pure organic substances</kwd><kwd>active pharmaceutical substances</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Материал статьи подготовлен в рамках государственного задания к Соглашению № 172-11-2023-002 от 09.02.2023 о предоставлении субсидий на безвозмездной и безвозвратной основе на возмещение затрат, связанных с осуществлением мероприятий в области обеспечения единства измерений «Разработка и совершенствование государственных первичных эталонов единиц величин, а также разработка и совершенствование государственных первичных референтных методик (методов) измерений».</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study reported in this publication was carried out as part of state assignment to Agreement No. 172-11-2023-002 dated 09.02.2023 on the provision of subsidies on a gratuitous and non-repayable basis to reimburse costs associated with the implementation of measures in the field of ensuring the uniformity of measurements «Development and improvement of state primary standards of units of measurement, as well as the development and improvement of state primary reference methods (methods) of measurements».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kaarls R., Quinn T.
