    The main chemical difference between the stationary phase and the mobile phase in reversed-phase HPLC can be described in various ways: we say that the water/organic phase is more polar while the alkyl bonded phase is less polar. We can describe the mobile phase as hydrophilic (water-loving) while the bonded phase is hydrophobic (water-hating).
