Size Exclusion Columns (SEC) / HPLC

GL Sciences offers size exclusion columns featuring diol phases for separation of large molecules in both aqueous and organic SEC. Size exclusion columns featuring large pore sizes are available for analyzing a broader range of molecular weights. Our SEC columns feature silica as base material allowing for higher maximum operating pressure than polymer base columns.
