Gel Permeation Chromatography (GPC), also known as Size Exclusion Chromatography, is a technique that employs columns to separate polymers and proteins according to their hydrodynamic volume in order to determine molecular size and weight.
The light scattering Viscotek 302-040 GPC Triple Detector provides a direct measurement of molecular weight and eliminates the need for column calibration.
The viscometer detector provides a direct measurement of intrinsic viscosity and allows the determination of molecular size, conformation and structure.
Concentration is measured with an RI or UV and is necessary for the determination of both molecular weight and intrinsic viscosity.
