WebTalk:Gel filtration chromatography From Wikipedia, the free encyclopedia Jump to navigationJump to search Permeation and filtration? [edit] This page lists gel permeation chromatography as a different method. Are not gel permeation, gel filtration, gel exclusion, size exclusion, and molecular sieve all the same thing? Gel permeation chromatography (GPC) is a type of size-exclusion chromatography (SEC), that separates analytes on the basis of size, typically in organic solvents. The technique is often used for the analysis of polymers. As a technique, SEC was first developed in 1955 by Lathe and Ruthven. The term gel … See more GPC separates based on the size or hydrodynamic volume (radius of gyration) of the analytes. This differs from other separation techniques which depend upon chemical or physical interactions to separate analytes. … See more Instrumentation Gel permeation chromatography is conducted almost exclusively in chromatography columns. The experimental … See more As a separation technique, GPC has many advantages. First of all, it has a well-defined separation time due to the fact that there is a final elution volume for all unretained analytes. Additionally, GPC can provide narrow bands, although this aspect of GPC is … See more Field-flow fractionation (FFF) can be considered as an alternative to GPC, especially when particles or high molar mass polymers cause clogging of the column, shear … See more GPC is often used to determine the relative molecular weight of polymer samples as well as the distribution of molecular weights. What GPC truly measures is the molecular volume and shape function as defined by the intrinsic viscosity. … See more Gel permeation chromatography (GPC) has become the most widely used technique for analyzing polymer samples in order to … See more There are disadvantages to GPC, however. First, there is a limited number of peaks that can be resolved within the short time scale of the GPC run. Also, as a technique GPC … See more

WebGel permeation / size exclusion chromatography (GPC/SEC) is the most well-known method for polymer and macromolecular analysis. As the technique ... Using multi-detector Advanced Polymer Chromatography (APC) to better differentiate samples by structure 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 … WebCategory:Gel permeation chromatography. Category. : Gel permeation chromatography.
