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.
Guard columns are recommended for challenging matrices or for use as trapping columns. YMC capillary guard columns are connected directly to the analytical column using the supplied column coupler.
A column coupler is supplied with every pack of YMC capillary guard cartridges to guarantee an optimum connection with low dead volume. A polymer-based (PCTFE) coupler is provided for 1/16” columns, while a stainless steel coupler is provided for 1/32” columns. Additional couplers can be purchased separately if required.
Columns, Guards and Accessories are only available for purchase online in North America or through our distributors.
To purchase consumables outside North America, please find your local distributor.
