Application Of Polymers

WebGel permeation chromatography (size-exclusion chromatography) can be used on humic acids or fulvic acids in water and is frequently applied to the analysis of fatty samples such as fish. Gel permeation chromatography is a very effective method based on differences in molecular mass. Ion exchange chromatography (usually referred to as ion chromatography) uses an ion exchange mechanism to separate analytes based on their respective charges. It is usually performed in columns but can also be useful in planar mode. Ion exchange chromatography uses a charged stationary phase to separate charged compounds including anions, cations, amino acids, peptides, and proteins. In conventional methods the stationary phase is an ion-exchange resin that carries … WebFeb 3, 2024 · Gel Permeation Chromatography - Basic Overview 4,577 views Feb 3, 2024 In this video I give a basic overview of GPC/SEC.

WebGel permeation chromatography (GPC), also known as size exclusion chromatography, has become the preferred technique for the determination of polymer molecular weight in the 21st century because of its capacity to determine all of the average molecular weights ( and ) in a short time. WebGelfiltrering, även känt som GPC (Gel Permeation Chromatography) är en kromatografisk metod för att separera proteiner och andra större molekyler baserat på storlek. När man utför gelfiltrering separerar en analyt baserat på dess storlek. Metoden kallas även SEC (Size Exclusion Chromatography).
