Цель работы – установление хроматографических и масс-спектральных характеристик  ряда токсичных химикатов, вновь внесенных в Список 1 Приложения по химикатам КХО, а именно,  N-(N,N-диэтилацетамидино) метилфторфосфоната (ДЭАМФ), N-(N,N-диэтилацетамидино)-О-метилфторфосфата (ДЭАОМФ) и N-(N,N-диэтилацетамидино)-О-этилфторфосфата (ДЭАОЭФ), и повышение квалификации специалистов лаборатории химико-аналитического контроля, принимающих участие в  профессиональных тестах, проводимых Организацией по запрещению химического оружия. Материалы  и методы исследования. Использовался метод высокоэффективной жидкостной хроматографии с тандемным  масс-спектрометрическим детектированием высокого разрешения (ВЭЖХ-МС/МСВР). Результаты исследования. В ходе работы проведена оптимизация условий масс-спектрометрического детектирования осущесвлен выбор оптимальных пар ионных реакций и программы градиентного элюирования при разделении  веществ в варианте обращенно-фазовой жидкостной хроматографии. Предложенный подход апробирован  при анализе модельных водных проб, оценены метрологические характеристики обнаружения данных соединений. Выводы. Установлено, что масс-спектры ДЭАМФ, ДЭАОМФ и ДЭАОЭФ, полученные в режиме электрораспылительной ионизации, содержат интенсивные пики, относящиеся к протонированным молекулярным ионам, которые в ходе дальнейшей фрагментации образуют характерные ионы-продукты, выявленные  в ходе проведенного исследования и использованные для идентификации и высокочувствительного обнаружения исходных веществ методом ВЭЖХ-МС/МСВР. Пределы обнаружения ДЭАМФ, ДЭАОМФ и ДЭАОЭФ  в водных пробах составили, соответственно, 1,0, 0,5 и 0,5 нг/мл</p></abstract><trans-abstract xml:lang="en"><p>The timely detection of violations of the Convention on the Prohibition of the Development, Production, Stockpiling  and Use of Chemical Weapons and on Their Destruction (CWC) requires reliable methods for detecting toxic chemicals  that can be used for chemical attacks. The purpose of this investigation is to estimate chromatographic and mass-spectral  characteristics of some toxic chemicals recently included into Schedule 1 of the Annex on Chemicals of the CWC,  in particular N-(N,N-diethylacetamidino)-methylfluorophosphonate (DEAMP), N-(N,N-diethylacetamidino)-O-methylfluorophosphate (DEAOMP) and N-(N,N-diethylacetamidino)-O-ethylfluorophosphate (DEAOEP) and the  improvement of the qualification of the Chemical Analytical Control Laboratory experts taking part in the OPCW  Proficiency Tests. Materials and methods. The technique of high efficient liquid chromatography coupled with tandem  high resolution mass spectrometry (LC-MS/HRMS) was used during the investigation. The results. The results of  optimization of conditions of mass-spectrometric detection, selection of optimal pairs of ion reactions and program of  gradient elution during separation of chemicals in reversed-phase liquid chromatography were presented. Presented  approach was tested in analysis of model aqueous samples; metrological parameters of detection of compounds  were estimated. Conclusion. It was shown during investigation that electrospray ionization mass-spectra of DEAMP,  DEAOMP and DEAOEP contain intensive peaks of protonated molecular ions, which after further fragmentation  produce characteristic product-ions used for identification and high sensitive detection of parent compounds by LC-MS/HRMS. Limits of detection of DEAMP, DEAOMP and DEAOEP were 1.0 ng/mL, 0.5 ng/mL and 0.5 ng/mL,  respectively</p></trans-abstract><kwd-group xml:lang="ru"><kwd>высокоэффективная жидкостная хроматография</kwd><kwd>Конвенции о запрещении разработки</kwd><kwd>производства</kwd><kwd>накопления и применения химического оружия и о его уничтожении</kwd><kwd>масс-спектрометрия  высокого разрешения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-resolution mass-spectrometry</kwd><kwd>high-efficiency liquid chromatography</kwd><kwd>Convention on the Prohibition  of the Development</kwd><kwd>Production</kwd><kwd>Stockpiling and Use of Chemical Weapons and on Their Destruction</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Федеральное государственное бюджетное учреждение «27 Научный центр» Министерства обороны Российской Федерации</funding-statement><funding-statement xml:lang="en">Federal State Budgetary Establishment «27 Scientific Centre» of the Ministry of Defence of the  Russian Federation.
