Designed specifically for the characterization of polyolefins, but with the ability to handle other polymers, such as polythiophene PEEK and PVF, the Viscotek High Temperature GPC (HT-GPC) system brings advanced triple detector technology to these demanding applications. 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
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 seven analytical GPC columns. The HT-GPC also features an in-line, self-cleaning filter system.
In all the configurations, the Vortex autoprep/autosampler is a significant new development in sample preparation and delivery for high temperature GPC. It consists of an integrated autosampling device and heated multivial stirrer so the sample is prepared with temperature control up to 170°C, then automatically injected according to the method schedule. This increases efficiency, enhances precision and promotes safety by removing the operator from the sample preparation process. The Vortex eliminates the need to transfer hot sample from a preparation vial to an autosampler vial and the HT-GPC filters the sample automatically on injection.
What makes the Viscotek HT-GPC unique?
- Intuitive and powerful software.
- Modular construction.
