YMC-Pack ODS-AQ Capillary Guard Columns

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.

Capillary Guard Columns: Features & Benefitsymca_3

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.
