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.
