Актуальность работы обусловлена расширением сферы применения изотопного анализа в различных областях, включая пищевую промышленность, экологический мониторинг и таможенный контроль. Существующие стандартные образцы имеют ограниченный диапазон аттестованных значений и вследствие введения санкций со стороны недружественных стран недоступны в России, что создает необходимость в разработке отечественных аналогов.</p><p>Цель исследования заключалась в создании и последующей аттестации метрологических характеристик стандартных образцов изотопного состава этанола, полученного из различного сырья: кукурузы, пшеницы, сахарной свеклы и синтетического этанола. Для достижения этой цели была разработана методика приготовления стандартных образцов, изготовлена опытная партия, проведены испытания на однородность, долговременную и кратковременную стабильность, определены аттестованные значения изотопного состава углерода, кислорода и водорода.</p><p>Основные методы изготовления и аттестации стандартных образцов включали изотопную масс-спектрометрию с использованием изотопного масс-спектрометра Isoprime precisION, автоматизированную фасовку и запайку ампул со стандартными образцами. Результаты исследования метрологических характеристик показали высокую однородность и стабильность разработанных стандартных образцов, что подтверждает их пригодность для использования в метрологических целях. Аттестованные значения разработанных стандартных образцов согласуются с известными литературными данными об изотопном составе этанола растительного происхождения (кукуруза и пшеница), что подтверждает надежность методов изотопного анализа и их применимость для идентификации биологических источников спирта.</p><p>Новизна исследовательской работы заключается в создании отечественных стандартных образцов с более широким диапазоном аттестованных значений изотопного состава углерода, кислорода и водорода по сравнению с аналогами, что расширяет возможности точных измерений и контроля в различных отраслях промышленности.</p><p>Практическая значимость описанного в статье исследования состоит в создании стандартных образцов для контроля качества алкогольной продукции, таможенного контроля и государственного контроля на алкогольном рынке. Разработанные стандартные образцы позволяют точно определять происхождение этанола, что особенно важно для идентификации биологических и синтетических источников.</p><p>Результаты исследования также открывают перспективы разработки стандартных образцов других веществ, таких как карбонат кальция, полиэтилен и монооксид углерода.</p></abstract><trans-abstract xml:lang="en"><p>The research presented in the article is aimed at developing reference materials (hereinafter referred to as RMs) for the isotopic composition of ethanol required for measurements in accordance with the requirements of Russian standards and Technical Regulations of the Customs Union. The relevance is due to the expansion of the scope of isotope analysis in various fields, including the food industry, environmental monitoring and customs control. Current reference materials have a limited range of certified values and are not available in Russia due to the imposition of sanctions by unfriendly countries, which creates the need to develop domestic analogues.</p><p>The purpose of the research is to create and subsequently certify the metrological characteristics of reference materials for the isotopic composition of ethanol obtained from various raw materials: corn, wheat, sugar beet and synthetic ethanol. For this purpose, a method for preparing reference materials was developed, a pilot batch was produced, tests for homogeneity, long-term and short-term stability were performed, and certified values of the isotopic composition of carbon, oxygen and hydrogen were determined.</p><p>The main methods of RM production and certification included isotope mass spectrometry using the Isoprime precisION isotope mass spectrometer (hereinafter referred to as IMS), automated packaging and sealing of ampoules with reference materials. The study of metrological characteristics showed high homogeneity and stability of the developed reference materials, which confirms their suitability for metrological purposes. The certified values of the developed reference materials are consistent with known literature data on the isotopic composition of plant-based ethanol (corn and wheat), which confirms the reliability of isotopic analysis methods and their applicability for identifying biological sources of alcohol. The novelty of the research work lies in the development of domestic reference materials with a wider range of certified values of the isotopic composition of carbon, oxygen and hydrogen compared to analogues, which extends the capabilities of accurate measurements and control in various industries.</p><p>The practical significance of the research is the development of new reference materials for quality control of alcoholic products, customs control and state control in the alcohol market. The developed reference materials provide accurate determination of the origin of ethanol, which is especially important for the identification of biological and synthetic sources.</p><p>The research results create opportunities for developing reference materials of other substances, such as calcium carbonate, polyethylene and carbon monoxide.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метрология</kwd><kwd>стабильные изотопы</kwd><kwd>изотопная масс-спектрометрия</kwd><kwd>стандартные образцы изотопов</kwd><kwd>стандартные образцы изотопного состава</kwd><kwd>этанол</kwd><kwd>изотопный состав этанола</kwd><kwd>пшеничный этанол</kwd><kwd>синтетический этанол</kwd><kwd>свекловичный этанол</kwd><kwd>кукурузный этанол</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metrology</kwd><kwd>stable isotopes</kwd><kwd>isotope mass spectrometry</kwd><kwd>isotope reference materials</kwd><kwd>isotope composition reference materials</kwd><kwd>ethanol</kwd><kwd>ethanol isotope composition</kwd><kwd>wheat ethanol</kwd><kwd>synthetic ethanol</kwd><kwd>beet ethanol</kwd><kwd>corn ethanol</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках ГК № 120-38/2023 от 17.05.2023 на выполнение опытно-конструкторской работы по теме «Разработка и выпуск новых комплексов стандартных образцов и мер для обеспечения единства измерений по приоритетным направлениям в целях технологического суверенитета Российской Федерации» (шифр ОКР «Суверенитет»).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The work was carried out within the framework of the Government Contract № ¬120-38/2023 dated 17.05.2023 for the implementation of experimental design work on the subject “Development and production of new sets of reference materials and measures to ensure the uniformity of measurements in priority areas for the purposes of technological sovereignty of the Russian Federation” (code of the Development Work “SUVERENITET”).</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">Arshad Z., Shin K.
