WebHydrophilic interaction liquid chromatography (HILIC) is a chromatographic technique used to improve the retention of strong polar substances in reversed-phase chromatography. It works by adopting a strong polar stationary phase and combining the mobile phase with a high proportion of organic phases. WebA range of stationary phases have been used for HILIC, including unbonded silica and materials bearing amide, polyol, amino, sulfobetaine, and other polar functionalities. 3,4 …
