The use of methods of highPperformance liquid chromatography _ tandem mass spectrometry with prePcolumn derivatization of the analyte can be considered promising. There are few official methods for quantitative determination of NDMH in aqueous samples thatmeet the necessary metrological requirements.</p></abstract><trans-abstract xml:lang="ru"><p>Обсуждаются преимущества и недостатки предлагаемых в научной литературе хроматографических подходов к определению 1,1-диметилгидразина (НДМГ) в воде хозяйственно-питьевого и культурно-бытового назначения. Сравнительный анализ и выбор оптимальных решений полезен при разработке высокочувствительных методик измерений массовой концентрации НДМГ в водных объектах на уровнях, соответствующих действующим гигиеническим нормативам. Можно считать перспективным использование методов высокоэффективной жидкостной хроматографии – тандемной масс-спектрометрии с предколоночной дериватизацией аналита.
