Предложен алгоритм оценки неопределенности содержания химического элемента в стандартном образце с учетом массы элемента в каждой составляющей смеси. Результаты, полученные расчетным способом по процедуре приготовления с использованием предложенного алгоритма, подтверждены методом Монте-Карло, а содержания элементов в смеси подтверждены результатами измерений методом атомно-эмиссионной спектрометрии с индуктивно связанной плазмой. Показана возможность применимости средневзвешенных оценок для характеризации стандартного образца многокомпонентного раствора.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents the results of a series of studies aimed at investigating the reference material (RM) of a multicomponent solution. An algorithm for estimating the uncertainty induced by the chemical element content in the RM is proposed taking into account the mass of the measurand in each component of the mixture. The results calculated according to the preparation procedure using the proposed algorithm were confirmed by the Monte Carlo method, while the elemental content in the mixture was confirmed via inductively coupled plasma optical emission spectroscopy. The applicability of weighted mean estimates for characterizing an RM of a multicomponent solution is shown.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многокомпонентный стандартный образец</kwd><kwd>неопределённость</kwd><kwd>чистые вещества</kwd><kwd>прослеживаемость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multicomponent reference material</kwd><kwd>uncertainty</kwd><kwd>pure substances</kwd><kwd>traceability</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">База данных «Эталоны сравнения в виде высокочистых веществ»: Уральский научно-исследовательский институт метрологии [сайт].
