Silica-based Size Exclusion Chromatography (SEC) Column
YMC-Pack Diol-SEC is a size exclusion chromatography column utilizing a dihydroxypropyl stationary phase bonded to a silica gel base. Diol-120, 200, and 300 are suitable for separation or molecular weight determination of proteins with molecular weights of 10,000 to several hundred thousand. Diol-60 is the most suitable for separation of peptides of oligosaccharides whose molecular weights are 10,000 or less.
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.
For SEC columns 8.0mm inner diameter and greater, we recommend using our standard guard columns with part numbers that end in -WTG.

YMC’s Guard Columns for HPLC are available in 4.0mm and 5.0mm diameters with 10mm lengths and 8.0mm diameters with 30mm 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.
