Sample preparation is based on extraction of analytes using QuEChERS with the following purification of extracts using SPE and concentration before chromatographic analysis. The procedure of sample preparation includes defatting using hexane and dispersive solid phase purification. Derivatization is carried out with the use of MSTFA under controlled temperature to obtain stable volatile derivatives suitable for GC–MS analysis. The quantitative characteristics of the method were obtained that included limits of detection (LOD) and limits of quantification (LOQ) for each of the studied bisphenols. For each analyte, a degree of extraction at three levels of introduction was calculated, being no less than 88%, which corroborates reproducibility and sufficient performance of the chosen scheme of sample preparation. Chromatographic conditions ensure separation of the studied bisphenols, except one critical pair, and stability of retained signals during serial analysis. For all compounds, characteristic mass spectra were obtained and ion transitions used for identification were determined. The presented method is suitable to a larger extent in research on studying factors that increase a degree of migration of bisphenols into foods. The paper presents all necessary stages for analysis of food products: detailed description of the process of sample preparation, protocol of derivatization, equipment for the GC–MS system. The process of sample preparation is designed for complex food matrices that require a high degree of purification for the following analysis.</p></abstract><trans-abstract xml:lang="ru"><p>В работе разработана и валидирована методика количественного определения шести из семи выбранных бисфенолов в пищевой продукции методом газовой хроматографии с масс-спектрометрическим детектированием после силилирующей дериватизации. Пробоподготовка основана на экстракции аналитов с использованием QuEChERS и последующей очисткой экстрактов ТФЭ и концентрированием перед хроматографическим анализом. Процедура пробоподготовки включает гексановое обезжиривание и дисперсную твердофазную очистку. Дериватизация выполняется с использованием МСТФА при контролируемой температуре для получения стабильных летучих производных, пригодных для ГХ–МС анализа. Получены количественные характеристики метода, включающие пределы обнаружения (LOD) и пределы количественного определения (LOQ) для каждого из исследуемых бисфенолов. Для каждого аналита рассчитана степень экстракции при трёх уровнях внесения, которая составляет не менее 88%, что подтверждает воспроизводимость и достаточную эффективность выбранной схемы подготовки пробы. Хроматографические условия обеспечивают разделение исследуемых бисфенолов, кроме одной критической пары, и устойчивость удерживаемых сигналов в ходе серийного анализа. Для всех соединений получены характерные масс-спектры и определены ионные переходы, используемые для идентификации. Представленная методика подойдет в большей степени исследовательских работ по изучению факторов, увеличивающих степень миграции бисфенолов в пищевые продукты. В статье приведены все необходимые этапы для исследования пищевой продукции: детальное описание процесса подготовки пробы, протокол дериватизации, инструментальные установки для ГХ–МС системы. Процесс подготовки пробы сделан для сложных пищевых матриц, которые требуют высокой степени очистки для последующего анализа.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Бисфенолы</kwd><kwd>ГХ–МС</kwd><kwd>пластификаторы</kwd><kwd>безопасность</kwd><kwd>пищевая продукция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bisphenols</kwd><kwd>GC–MS</kwd><kwd>plasticizers</kwd><kwd>safety</kwd><kwd>foods</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследования проводились в рамках государственного задания ФГБНУ «ФНЦ пищевых систем им.
