SEC functions also inside of a preparative way by trapping the more compact molecules from the pores of a particles. The larger sized molecules basically move through the pores as They are really too massive to enter the pores. Larger molecules thus circulation throughout the column more quickly than smaller molecules: that is certainly, the lesser the molecule, the longer the retention time.

Know your column: Columns have distinct pore sizes and solvent tolerances. Look at Together with the manufacturer from the column to forestall loading incompatible samples and solvents.
