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).

WebHILIC is a particularly useful separation mode for polar organic compounds that are poorly retained by reversed phase. Retention of these polar compounds using reversed phase methods is often difficult because of co-elutions with the solvent front or elutions within the chromatographic region where ion suppression is the greatest.

WebLike Normal Phase Chromatography, HILIC uses a polar stationary phase and a non-polar yet water-miscible mobile phase. It uses designed stationary phases instead of bare alumina or silica particles. HILIC fills a need in analytical separations and is used for the separation of very polar molecules like acids, bases, and zwitterions. fisherman bathroom decorWebApr 29, 2011 · Abstract.
