Gel Permeation/Size Exclusion (GPC/SEC)

Agilent- LC columns Gel Permeation/Size Exclusion (GPC/SEC) Gel permeation chromatography (GPC) and size exclusion chromatography (SEC) are names applied to the most popular technique for measuring the molecular weight distribution of natural and synthetic polymers, a property that affects many of the physical parameters of materials such as strength, toughness and chemical resistance.
GPC and SEC are liquid chromatographic techniques that separate individual polymer chains on the basis of their size in solution and not on their chemistry.
Gel permeation chromatography (GPC) is the name used to describe the analysis of polymers in organic solvents, such as tetrahydrofuran.
Size exclusion chromatography (SEC) is the name used to describe the analysis of polymers in water and water-based solvents, such as buffer solutions.
GPC/SEC is the only established method for obtaining a comprehensive understanding of a polymer’s molecular weight distribution.
Agilent offers a comprehensive portfolio of GPC/SEC columns and calibrants for high performance separations based on molecular size in solution.

• A portfolio for analysis of synthetic and natural polymers.

• A wide selection of polymer standards to cover the range of applications in organic and water based solvents.

• PL aquagel-OH-series, for aqueous SEC separations, and PLgel, for organic polymer applications, are available in mixed and individual pore sizes across a range of particle sizes, to cover the full spectrum of molecular weights.

• Prep scale columns are available, along with narrow bore columns and columns designed for specific applications.
