WebHydrophilic Interaction Liquid Chromatography (HILIC) HILIC is a chromatographic technique for the retention and separation of problematic polar compounds. In HILIC mode, water acts as the strongest solvent to effectively elute analytes off the column, and the organic solvent acts as the weak solvent. This is opposite to reversed phase ... WebHILIC columns are less tolerant of short equilibration times than RPLC columns, mainly because the water in the aqueous layer within the stationary phase derives from the mobile phase and takes time to …
