Ultisil Specialized C18

This specialized set of C18 phases is designed to offer nuanced differences from traditional C18/ODS phases. For example, Ultisil AQ-C18 and Ultisil ODS-3 will perform well even with 100% aqueous mobile phase; Ultisil XS-C18 is high-carbon-loaded, improving its steric hindrance selectivity. Also see specialized C18 phases for Polynuclear Aromatic Hydrocarbons (PAH) and Amino Acid analysis.
