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. … 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. … 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. … See more Gel permeation chromatography (GPC) has become the most widely used technique for analyzing polymer samples in order to determine their molecular weights and weight … 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 … See more WebGPC Medical USA, Inc. is an orthopaedic implant company with offices in Dallas, Texas.
