Пошагово, с пояснениями и примерами рассмотрено установление значимых (потенциально критических) факторов, а так же определение допустимых пределов изменения значимых факторов и откликов. Оценка этих пределов важна для обоснования требований к пригодности хроматографической системы. Даны рекомендации по выполнению необходимых вычислений в Excel и оценке робастности хроматографических методик.</p></abstract><trans-abstract xml:lang="en"><p>This article covers the theoretical and practical basics of research of the robustness of chromatographic methods on the base of Plackett - Burman design. Step by step, with explanations and examples, the estimation of significant (potentially critical) factors as well as the estimation of permissible limits of the changes of factors and responses are considered. The assessment of the limits is important for the justification of the requirements to the suitability of a chromatographic system. Also, we suggest the recommendations for performing necessary calculations in Excel and for the assessment of robustness of chromatographic methods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>робастность</kwd><kwd>планы Плакетта - Бермана</kwd><kwd>риск</kwd><kwd>валидация</kwd><kwd>хроматографические методики</kwd><kwd>пригодность системы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>robustness</kwd><kwd>Plackett - Burman design</kwd><kwd>risk</kwd><kwd>validation</kwd><kwd>chromatographic methods</kwd><kwd>system suitability</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">Эпштейн Н.
