Detector Array with UV-LS-RI-VISC
The Tetra Detector Array is a GPC/SEC multiple detector for the characterization of natural and synthetic polymers, biopolymers and proteins. It comprises a low angle light scattering (LALS) detector, four capillary viscometer detector, refractometer and selectable wavelength UV-Vis. All the detectors, as well as the GPC columns, are contained within a heated oven compartment with temperature control to 80 C so there is no variation in the samples. The integration and proprietary arrangement of detectors (UV-LS-RI-VISC) insures minimal inter-detector volumes and reduced band-broadening, as well as eliminates the dilution effect and viscometer breakthrough experienced when the RI is placed last in the series. Applications include identifying absolute molecular weight, molecular size, intrinsic viscosity, branching, conformation and copolymer composition.
