Amino Column with Improved Durability
YMC-Pack Polyamine II is a silica-based, normal-phase stationary phase bonded with polyamine that is particularly useful for the separation of sugars. The column lifetime in aqueous mobile phases is longer than conventional silica-based amino columns and is therefore applicable for the separation of oligosaccharides using high-aqueous mobile phases. In addition, YMC-Pack Polyamine II can be used to separate ionic compounds with a combination of normal-phase and weak anion-exchange modes.
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.

Sold Individually
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)
