Liquid chromatography Gel Permeation Chromatography (GPC) Gel Permeation Chromatography (GPC) for measurement of polymer molecular weight, size and structure. Gel Permeation Chromatography (GPC) is an analytical technique that separates dissolved macromolecules by size based on their elution from columns filled with a porous gel.
GPC/SEC Calibration Kits. A calibration kit consists of 8 to 12 well-characterized standards of one polymer type with different molar masses. The kit documentation includes a calibration report showing the calibration curve prepared with the individual standards and certificates of analysis for each individual standard.

Jul 1, 2006 · GPC-SEC system. A precise solution for polymer characterization Gel Permeation Chromatography (GPC), also referred to as Size Exclusion Chromatography (SEC), is the technique of choice to characterize polymers. Average molecular weights and molecular weight distributions are calculated based on the elution behavior in a size exclusion column set.
Aijiren PolarGel-L GPC Columns. For analysis of low molecular weight polymers in polar solvents. Specifically designed for polar samples. Mixed bed technology delives near linear calibrations for greater accuracy. Mechanical stability for longer column lifetimes.
The most common chromatographic method for the analysis of polymers is Gel Permeation Chromatography (GPC) where the separation is based upon the size of the polymer sample in solution, or the hydrodynamic volume of the polymer solution.Figure 1 shows the chromatograms obtained using GPC for a polystyrene sample, polystyrene-acrylonitrile
GPC-IR® | High Temperature GPC/SEC System for PolyolefinsThe built-in IR detector provides industry-leading characterization of polymers such as High-Density Polyethylene ( HDPE ) Tel: +8618057059123
GPC separates molecules on the basis of hydrodynamic size (not Mw). The large molecules move more rapidly through the GPC column, and in this way the mixture can be separated. The elution volume of a molecule is related to its hydrodynamic volume. To relate the elution volume to the molecular weight of a polymer, a calibration with molecular weight standards is needed.
