The commonest RP stationary phases are based on a silica support, which is area-modified by bonding RMe2SiCl, where R is usually a straight chain alkyl group such as C18H37 or C8H17.
You will also find polymeric hydrophobic particles that serve as stationary phases, when methods at Severe pH are needed, or hybrid silica, polymerized with natural substances. The longer the hydrocarbon ligand about the stationary section, the for a longer time the sample factors may be retained. Most of the present ways of separation of biomedical supplies use C-18 variety of columns, at times identified as by a trade names like ODS (octadecylsilane) or RP-18 (Reversed Period 18).
