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 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.

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.
