Triple Detector gel-permeation chromatography/size-exclusion chromatography (GPC/SEC) system

Designed for macromolecular characterization, the Triple Detector gel-permeation chromatography/size-exclusion chromatography (GPC/SEC) system features an integrated triple detector array (TDA) comprised of a unique low-angle light-scattering (LALS) detector, four capillary viscometer detectors; a GPCmax pump, autosampler and degasser module; and OmniSEC software for multiple detection analysis and complete system control. In a single GPC/SEC experiment, this system can provide absolute molecular weight without the column calibration, extrapolations or corrections required by other techniques. It can also determine molecular size (to less than 1 nm), intrinsic viscosity, as well as information on structure, conformation, branching, aggregation and copolymer composition.
