Useful in Both Normal-Phase and Reversed-Phase Modes
YMC-Pack CN can be used for both normal-phase and reversed-phase analyses due to the medium polarity of the cyanopropyl phase bonded to the silica base particle. It can be used in normal-phase with low-polarity mobile phases such as hexane, or in reversed-phase with highly-polar mobile phases such as methanol and water. YMC-Pack CN can be useful for shortening analysis time in situations where retention is substantial using C18 or C8, or when separation optimization is difficult.
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.
(No holder required)
