The Use of a Chromatographic Column Packed With Amide Sorbent for the Analysis of Parabens

Abstract: Резюме. На основании опыта использования метода жидкостной хроматографии гидрофильных взаимодействий для анализа соединений различной природы исследована возможность применения хроматографической колонки XBridge Amide 150×4,6 мм для разделения эфиров 4-гидроксибензойной кислоты (парабенов). Сравнивались времена удерживания, порядок выхода и разрешение между пиками парабенов и примеси А (4-гидроксибензойная кислота) при использовании подвижных фаз ацетонитрил-фосфатный буфер с содержанием ацетонитрила 7-10 % и … Show more
