Most Polar Reversed-Phase Column
In reversed-phase mode, cyano columns are the most polar and least retentive of all reversed-phase packings. Extremely hydrophobic compounds which do not elute in standard C18 and C8 packings can be retained using typical reversed-phase eluents. In addition, the unique nitrile chemistry provides different selectivity from both phenyl and standard aliphatic (C18, C8, and C4) reversed-phase packings. Large pore-size 300Å packing materials are also available for the analysis of biomolecules in order to utilize this unique selectivity.
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.

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.
