The main applications of normal-phase liquid chromatography are its use to separate

analytes that have low water solubility and those that are not amenable to reversed phase liquid chromatography.

Reversed-phase liquid chromatography form of liquid chromatography, which has many similarities with hydrophobic interaction chromatography (HIC).
