Description

 

Advanced triple detection, using RI, UV, light scattering and a viscometer, for demanding applications.

The Viscotek HT-GPC is a complete GPC system designed specifically for the molecular weight and structure characterization of polyolefins, with no bulk filtration of sample, and with the ability to handle other polymers, such as polythiophene, PEEK and PVF that require temperatures from approximately 100°C up to 160°C to stay in solution.

The HT-GPC system includes a high temperature RI, for use as a concentration detector, a light scattering detector for absolute molecular weight determination and a viscometer for intrinsic viscosity determination and branching. All of these detectors are optionally so the system can be customized to conventional and universal calibration systemsIt also features a temperature controlled column chamber and automated filtering of the sample at high temperature, to ensure safe handling.


Viscotek HT-GPC Features:

  • Dual piston pump optimized for HT-GPC, with extremely low pulsation and stable eluent flow to improve detector performance.
  • Temperature controlled environment for up to 7 columns, injector and up to three detectors. Operates up to 160°C
  • Automated sample preparation using the Vortex autoprep/autosampler. Operates up to 170°C with no user intervention, making the system safe, accurate and productive.
  • Automated sample filtration reduces the number of preparation steps - only the sample injected on the column is filtered, which avoids bulk filtration and improves lab safety (no manual handling of hot solvents).
  • High sensitivity viscometer, with unrivalled baseline stability and the widest application flexibility.
  • Digital Inert Transducer (DIT) technology for faster, more sensitive response.
  • Unique 7° Low Angle (LALS) detector measures the absolute MW directly without data fitting, extrapolation or correction.
  • 90° Right Angle (RALS) detector provides the best signal to noise ratio and the highest sensitivity for small molecules.
  • Accurate measurement of the polymer concentration using a refractive index detector.
