HILIC or Hydrophilic Interaction Liquid Chromatography is a high-performance liquid chromatographic (HPLC) technique for separation of polar and hydrophilic compounds. Originally the separation technique was called "Hydrophilic-Interaction Chromatography", and occasionally the expression "Aqueous Normal Phase" has also been used.
