Join our seminar that will focus on the Characterization of Proteins & Natural and Synthetic Polymers Using Quad Detector Size Exclusion Chromatography this month.
OMNISEC is the totally new GPC/SEC system from Malvern. It is a complete system for sample separation and detailed molecular characterization. The technology has advanced, however, and with additional detectors comes a wealth of information. Light scattering detectors, whether SEC-MALS, RALS, or LALS (multi-angle, right-angle or low-angle light scattering), measure absolute molecular weight and molecular weight distribution with excellent accuracy.
A viscometer allows measurement of molecular structure and branching, and multiple concentration detectors allow compositional analysis of copolymers. The combination of these detectors allows for complete characterization of polymers without the compromises of relative measurements or chromatography setup dependencies.
