Web1 day ago · HILIC separations occur through interaction of the analytes in an organic-rich mobile phase with the aqueous layer formed at the surface of the polar stationary phase. Sufficient retention of highly polar compounds is granted due to various intermolecular interactions contributing to the overall polar character of the analyte: dipole-dipole, H ... WebHILIC uses the same mobile phases and systems as the more common reversed-phase liquid chromatography (RPLC). However, it employs a polar stationary phase to separate potentially problematic polar analytes and retain charged compounds, including inorganic salts.
WebThis technique can be described as a variation of reversed phase chromatography performed using a polar stationary phase. The mobile phase employed in HILIC is highly … WebHydrophilic interaction liquid chromatography, or HILIC, is a powerful mode of liquid chromatography (LC)that uses polar stationary phases and high-organic initial mobile phase conditions for the separation of polar analytes.
