In reverse phase chromatography, the stationary phase is made :
Reversed-Phase Liquid Chromatography ( RPLC) uses a hydrophobic or nonpolar stationary phase and a hydrophilic or polar mobile phase. The stationary phase is commonly composed of porous silica particles linked to alkyl chains (C4, C5, C8, C18) or other inert nonpolar substances such as divinylbenzene (DVB).
