High temperature GPC chromatograph
max. 160°C | Viscotek HT-GPC Malvern Instruments

Designed specifically and exclusively for the characterization of polyolefins, the Viscotek High Temperature GPC (HT-GPC) system brings advanced triple detector technology to this demanding application. The HT-GPC operates up to 160°C to handle even the toughest polypropylene samples and is engineered in a modular format for flexibility, reliability and easy maintenance.

The system is available in four detector configurations:

- Conventional Calibration - using RI (refractive index) detection with column calibration
- Light Scattering - using RI + light scattering (LALS) detection for direct molecular weight measurement without column calibration.
- Universal Calibration - using RI + Viscometer detection to give true molecular weights plus branching data.
- Triple Detection - using RI + Viscometer + light scattering (LALS) for direct molecular weight measurement and branching data.

In the full triple detector configuration the Viscotek HT-GPC system will provide absolute molecular weight without extrapolation or correction, molecular size (Rg and Rh), intrinsic viscosity and branching in a single GPC/SEC experiment.

All detectors reside within a temperature-controlled oven compartment which has space for four analytical GPC columns. The HT-GPC also features an in-line, self-cleaning filter system.
