WebbThe Rate Theory of Chromatography: A more realistic description of the processes at work inside a column takes account of the time taken for the solute to equilibrate between the stationary and mobile phases (unlike the plate model, which assumes that equilibration … WebbSize 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.
