Size Exclusion-CQP

Size Exclusion Chromatography (SEC) is a technique used to separate molecules based on their size and molecular weight rather than their chemical interactions. It is also known as gel filtration chromatography (GFC) in aqueous systems and gel permeation chromatography (GPC) in organic solvents.

Size exclusion chromatography columns

Size exclusion chromatography is a liquid chromatographic technique which separates solute molecules according to their size in solution. The column is packed with porous particles and separation takes place as a result of the differential solute distribution outside and within the pores of the packing material. Solute molecules which are larger than the pores of the packing material will be excluded and therefore will elute first and have a lower retention time than the smaller one. The CQP series columns based on a hydrophilic polymer are designed for analysis of water soluble polymers such as oligosaccharides and PEG, etc.
