Size-exclusion chromatography (SEC), also known as molecular sieve chromatography, is a chromatographic method in which molecules in solution are separated by their size, and in some cases molecular weight. It is usually applied to large molecules or macromolecular complexes such as proteins and industrial polymers. Typically, when an aqueous solution is used to transport the sample t… Webbgraphy,[26] gel-filtration chromatography, and gel-permeation chromato-graphy. The first examples of size-based separations by liquid chromatography were noted by Wheaton and Bauman[27] in their work on ion-exclusion chromatography. They observed that various nonionic species could be separated on ion-exchangers by a size-based mechanism.
