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 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.
