Tetra Detector Array

The Tetra Detector Array uses state-of-the-art GPC/SEC multiple detection technology for the characterization of natural and synthetic polymers, biopolymers and proteins. It consists of a patent-pending 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, thus eliminating temperature variations. The integration and unique, proprietary arrangement of detectors (UV-LS-RI-VISC) insures minimal inter-detector volumes and reduced band-broadening, as well as eliminating the dilution effect and viscometer breakthrough experienced when RI is placed last in the series.
