WebHydrophilic compounds - compounds with a better solubility in water than in organic solvents, or completely non- soluble in organic solvents (et. acetonitrile, ethanol). Examples of such compounds are amino acids, sugars, peptides, nucleotides, protonated amines and any other molecules with one or several polar groups (Fig. 1). WebHydrophilic interaction liquid chromatography (HILIC) is a popular technique for the separation of polar compounds, which are poorly retained by reversed-phase liquid chromatography. Despite the versatility and the potentiality of this technique, many analysts still feel uncomfortable when approaching it.
