In RPLC the stationary phase is non-polar and the mobile phase relatively polar, hence the name reversed-phase

In RPLC stationary phase most commonly used is in the bonded-phase form, in which alkylsilane groups are chemically attached to silica. Butyl (C4), octyl (C8) and octadecyl (C18) silane groups are most commonly used.

Reversed-phase liquid chromatography differs from most other forms of chromatography in that the stationary phase is essentially inert and only non-polar (hydrophobic) interactions are possible with analytes.

Proteins differ in the amount of hydrophobic amino acids that are present on their surface. This difference can be exploited in salt fractionation but can also be used in a higher resolution method using hydrophobic interaction chromatography (HIC).
