Size Exclusion Chromatography SEC also known as Gel Permeation Chromatography GPC or Gel Permeation Chromatography (GPC), also known as Size Exclusion Chromatography (SEC), or Gel Filtration Chromatography (GFC) is a chromatographic technique that separates dissolved molecules on the basis of their size by pumping them through specialized columns containing a microporous packing material.
As the sample is separated and elutes from the column, it can be characterized by a single concentration detector (Conventional Calibration) or series of detectors (Universal Calibration and Triple Detection).
This technique is used to characterize natural and synthetic polymers, biopolymers, proteins or nanoparticles.
When the Size Exclusion Chromatography separation is coupled with light scattering, viscometer and concentration detectors together (triple detection), it will provide a distribution of absolute molecular weight, molecular size, and intrinsic viscosity as well as information on macromolecular structure, conformation aggregation and branching.
