YMC-Pack ODS-AQ Analytical 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.

Guard Cartridges

Analytical Guard Cartridges: Features & Benefits

YMC’s Guard Column Cartridge Systems for HPLC accept cartridges of 1.0, 2.1, 3.0, or 4.0mm inner diameters – in either 10mm or 20mm lengths.  Cartridges are available with a comprehensive selection including all stationary phase chemistries offered by YMC, ensuring compatibility between the guard column and the analytical column.  Assembly is tool-free, simplifying cartridge replacement.

YMC Guard Column Cartridges require the use of a holder, P/N: XPGCHP1 for 10mm length and P/N: XPGCHP2 for 20mm length.

Guard Columns

Analytical Guard Columns: Features & Benefits

YMC’s Guard Columns for HPLC are available in 4.0mm and 5.0mm diameters and come in 10mm lengths.  These guard columns are available with a comprehensive stationary phase selection offered by YMC, ensuring compatibility between the guard column and the analytical column.  Unlike our guard cartridge columns, these guard columns do not require a holder, but do require a small jumper made from either stainless steel or PEEK tubing in order to connect them to the inlet of the analytical column.
