WebHILIC or hydrophilic interaction liquid chromatography is a high-performance liquid chromatographic (HPLC) technique for separation of polar and hydrophilic compounds. Simply put, HILIC is a normal-phase type of separation but uses reversed-phase type eluents. WebMay 12, 2024 · Professor Alpert introduced a new concept in 1990: hydrophilicity chromatography (HILIC). This chromatographic method is used to separate strong polar and hydrophilic compounds, such as nucleosides and nucleotides, amino acids, sugars, etc. Besides, it uses polar stationary phase, polar mobile phase, and solutions with lower … WebSlide 15: HILIC (Hydrophilic Interaction Liquid Chromatography) Hydrophilic Interaction Liquid Chromatography (HILIC) is the modern adaptation of Normal Phase … fisherman bathroom
