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 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.
