YMC-Pack ODS-AQ Semi-Prep 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

Semi-Prep Guard Cartridges: Features & Benefits

YMC’s Guard Column Cartridge Systems for Semi-Prep HPLC utilize cartridges of 10, 20, or 30mm inner diameters – in 10mm 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 (including columns by other manufacturers).  Assembly is tool-free, simplifying cartridge replacement.

YMC Guard Column Cartridges require the use of a holder, P/N: XPCHSPW1 for 10mm I.D., P/N: XPCHSPW2 for 20mm I.D. and P/N: XPCHSPW3 for 30mm I.D.

Guard Columns

Semi-Prep Guard Columns: Features & Benefits

YMC’s semi-preparative & preparative Guard Columns for HPLC are available in 10mm diameter with 30mm length as well as 20mm, 30mm, and 50mm diameters with 50mm lengths.  These guard columns are available with a comprehensive stationary phase selection offered by YMC, ensuring compatibility between the guard column and the semi-preparative or preparative column.  Unlike our guard cartridge columns, these guard columns do not require a holder.
