YMC Diol-NP Analytical Guard Columns

Different Separation Characteristics from Bare Silica Gel

YMC-Pack Diol-NP shows typical normal-phase retention behavior when used with low-polarity mobile phases due to hydroxyl groups on the surface of the stationary phase acting as polar groups.  Diol-NP is as widely applicable to normal-phase separations as standard silica gel, but is useful in cases where separation optimization is difficult to achieve with silica.  In addition, it can also be used in HILIC-mode with organic/water mobile phases.

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.
