Разработка стандартных образцов проведена в несколько этапов: идентификация, характеризация, исследование однородности и стабильности материалов стандартных образцов. Идентификация материалов-кандидатов в стандартные образцы проведена методом ИК Фурье спектроскопии и путем определения температуры плавления методом дифференциального термического анализа. Характеризация материалов-кандидатов в стандартные образцы выполнена косвенным методом «сто минус сумма примесей» с подтверждением результатов измерений прямым методом – методом кислотно-основного титрования. Установлено, что результаты измерений массовой доли основного вещества бензойной и сорбиновой кислот, полученные методом кислотно-основного титрования и методом массового баланса, согласуются между собой с учетом значений расширенных неопределенностей. Работа выполнена с привлечением первичных и вторичных эталонов. Повышение точности результатов измерений массовой доли основного вещества достигнуто путем поиска и подбора оптимальных режимов проведения измерений при определении каждого вида примеси. Определение однородности материалов проведено методом однофакторного дисперсионного анализа, определение стабильности проведено методом регрессионного анализа. Разработанные  стандартные  образцы  состава  бензойной  и  сорбиновой  кислот  внесены в Федеральный информационный фонд по обеспечению единства измерений под номерами ГСО 12297–2023 и ГСО 12298–2023. Аттестованное значение массовой доли основного вещества находится в диапазоне от 95,00 до 100,00 %, границы допускаемых значений абсолютной погрешности при Р = 0,95 составляют ± 0,5 %.</p><p>Использование ГСО 12297–2023 и ГСО 12298–2023 для аттестации и контроля точности методик, установления и контроля стабильности градуировочных (калибровочных) характеристик средств измерений, поверки, калибровки средств измерений способно повысить качество пищевых продуктов, продовольственного сырья и фармацевтических препаратов.</p></abstract><trans-abstract xml:lang="en"><p>The article introduces the development of reference materials of benzoic and sorbic acids with a certified value of the mass fraction of the main substance. The development of reference materials was carried out in several stages: identification, characterization, study of homogeneity and stability of reference materials. Identification of candidate materials for reference materials was carried out by IR Fourier spectroscopy and determination of melting point by differential thermal analysis. The candidate materials for reference materials were characterized by the indirect method «one hundred minus the sum of impurities» with confirmation of the measurement results by the direct method – the acid-base titration method. It was established that the measurement results of the mass fraction of the main substance of benzoic and sorbic acids obtained by the acid-base titration method and the mass balance method are consistent with each other taking into account the values of expanded uncertainties. The work was carried out using primary and secondary standards. The accuracy of the measurement results of the mass fraction of the main substance was increased by searching for and selecting optimal measurement modes when determining each type of impurity. The homogeneity of materials was determined using the one-way analysis of variance method; stability was determined using the regression analysis method.</p><p>The developed reference materials of benzoic and sorbic acids were included in the Federal Information Fund for Ensuring the Uniformity of Measurements as GSO 12297–2023 and GSO 12298–2023. The certified value of the mass fraction of the main substance is in the range from 95.00 to 100.00 %, the limits of the permissible values of the absolute error at P = 0.95 are ± 0.5 %.</p><p>The use of GSO 12297–2023 and GSO 12298–2023 for certification and control of the accuracy of methods, establishment and control of the stability of calibration characteristics of measuring instruments, verification, calibration of measuring instruments can improve the quality of food products, food raw materials and pharmaceuticals.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эталон</kwd><kwd>стандартный образец</kwd><kwd>газовая хроматография</kwd><kwd>жидкостная хроматография</kwd><kwd>прослеживаемость результатов измерений</kwd><kwd>бензойная кислота</kwd><kwd>сорбиновая кислота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>standard</kwd><kwd>reference material</kwd><kwd>gas chromatography</kwd><kwd>liquid chromatography</kwd><kwd>traceability of measurement results</kwd><kwd>benzoic acid</kwd><kwd>sorbic acid</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено при финансировании по Государственному контракту № 120 –38/2023 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») от 17 мая 2023 г.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was carried out with funding under State Contract No. 120–38/2023 dated May 17, 2023 for the performance of research and development under the following topic: «Development and production of new complexes of reference standards and measures to ensure the uniformity of measurements in the priority areas for the purposes of securing technological sovereignty of the Russian Federation» (R&amp;D code: «Sovereignty»).</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">Применение подвижных фаз с ион-парными реагентами для разделения смесей бензойной и сорбиновой кислот / А.
