Hilic phase
WebHILIC has been gaining popularity in recent years due to the increased retention of polar compounds and the alternative selectivity HILIC chromatography offers to reversed-phase. In addition, the HILIC mode is highly compatible with mass spectrometric (MS) and evaporative light scattering (ELSD) detection due to the volatility of the mobile phase. WebHILIC (Hydrophilic Interaction Liquid Chromatography) is not a new mode of separation, but rather a variation of normal phase liquid chromatography (NPLC), in which sample components distribute between a polar stationary phase and a less polar mobile phase.

WebSlide 15: HILIC (Hydrophilic Interaction Liquid Chromatography) Hydrophilic Interaction Liquid Chromatography (HILIC) is the modern adaptation of Normal Phase … WebThe typical mobile phase for HILIC chromatography includes MeCN with a small water content. It is commonly believed that in HILIC, the mobile phase forms a water rich layer on the surface of the polar stationary phase …
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. WebHILIC or hydrophilic interaction liquid chromatography is a high-performance liquid chromatographic (HPLC) technique for separation of polar and hydrophilic compounds. …
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 ... 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.
