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 design is not much different from other techniques of liquid chromatography. … 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 … 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 … 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 Field-flow fractionation (FFF) can be considered as an alternative to GPC, especially when particles or high molar mass polymers … See more
