WebHILIC Overview. HILIC can be described as a variation of reversed phase chromatography performed using a polar stationary phase. The mobile phase employed is highly organic in nature (> 60-70% solvent, typically acetonitrile) containing a small percentage of aqueous solvent/buffer or other polar solvent. The water in the mobile phase forms an ... 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 ... flmry-a
