What is the separation principle in size exclusion chromatography? Size exclusion chromatography (SEC) separates molecules based on their size by filtration through a gel. The gel consists of spherical beads containing pores of a specific size distribution. Separation occurs when molecules of different sizes are included or excluded from the pores within the matrix.
What is the principle of gel exclusion chromatography? Principle. The gel filtration chromatography is based on the molecular size and the hydrodynamic volume of the components. The molecules are separated by the differential exclusion or inclusion of solutes as they pass through the stationary phase containing heteroporous cross-linked polymeric gel or beads.
How do you optimize separation in size-exclusion chromatography? Optimize the separation at small scale, with, for example, Superdex Increase 10/300 or HiLoad 16/600 column formats. Maintain the sample-to-column volume ratio. Maintain the bed height and increase the column volume by increasing the cross-sectionalarea of the column.
What is the purpose of size-exclusion chromatography? Size-exclusion chromatography (SEC) is a chromatographic technique used for separating substances according to their molecular size, or more correctly, hydrodynamic volume.
