WebbSize Exclusion Chromatography: This type of chromatography involves the separation of different components of the mixture based on their sizes. In size exclusion … 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.

28.7: Size-Exclusion Chromatography - Chemistry LibreTexts
WebbSize-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 … WebbSize exclusion chromatography columns are commercially available with a group (series) of different packing material pore sizes (different exclusion limits). For column selection, a column capable of determining the target range of … WebbSize exclusion chromatography: solid (microporous beads of silica) liquid: size of molecules: small molecules get trapped in the pores of the stationary phase, while large molecules flow through the gaps between the beads and have very small retention times. So larger molecules come out first. island oasis mango puree
