RP / hydrophobic and pH stable C18 columns for more unpolar analytes in Reversed Phase (USP L1)

C18 stationary phase with a special, high efficiency or polymeric unpolar endcapping style. Because of the high carbon content and the protection of the Silica gel these materials are also suited for the use of mobile phase in an extended pH range from typically pH 1-12.

While a high endcapped C18 phase is characterized mostly by the high carbon content, a polymeric endcapped phase also provides an increased steric selectivity.
