Useful for Separations Using High Aqueous Mobile Phases
YMC-Pack ODS-AQ is a unique reversed-phase material with both a hydrophobic high carbon loading and a relatively hydrophilic surface. Because of the hydrophilic surface, ODS-AQ can be “wetted” with polar eluents. ODS-AQ provides chromatographers reproducible retention and excellent peak shape in highly aqueous mobile phases, even 100% water; a condition that is often difficult to use with conventional ODS packings.
Strong Retention for Polar Compounds
In highly aqueous mobile phases, ODS-AQ gives longer retention than conventional ODS packings. This is due to the C18 ligands on ODS-AQ actually being lifted from the surface by the action of the eluents penetrating the silica pores.
