Product: Multiple detector array analyzes polymers, proteins

Instrumentation & Sensors

Using Viscotek's Tetra Detector Array, you can obtain absolute molecular weight, molecular size (to less than 1 nm), and intrinsic viscosity, as well as information on branching, conformation, aggregation and copolymer composition, all in a single GPC/SEC experiment.

If you manufacture natural or synthetic polymers, biopolymers, or proteins, the Tetra Detector Array from Viscotek offers sophisticated GPC/SEC multiple detection technology for product characterization. The instrumentation array includes a low-angle light-scattering (LALS) detector, four capillary viscometer detectors, refractometer, and selectable wavelength UV/VIS.

With this combination of sensors, it can reportedly characterize:

  • Absolute molecular weight;

  • Molecular size;

  • Intrinsic viscosity;

  • Branching;

  • Conformation; and,

  • Copolymer composition.

All the detectors, as well as the GPC columns, are contained within a heated oven compartment with temperature control to 80 °C (175 °F), which means your sample never sees a temperature variation/ The integration and unique, proprietary arrangement of detectors (UV-LS-RI-VISC) ensures minimal inter-detector volumes and reduced band-broadening, and eliminates the dilution effect and viscometer breakthrough experienced when the RI is placed last in the series.
