EcoSEC™ High Temperature System
Demanding high temperature polymer analyses, such as for polyolefins, require a system that delivers results reliably, reproducibly, and produces these results in an easy to use, safe instrument. The EcoSEC High Temperature GPC System incorporates the proven design and technology used in our ambient EcoSEC Elite™ GPC System.
The dual pump system, dual flow RI detector, spacious column oven, total system temperature control, autosampler, sample prep station, safety features, and all-in-one design controlled by intuitive software combine to deliver exceptional performance.
The EcoSEC High Temperature GPC System can be upgraded with a High Temperature Viscometer Detector.

| Total system temperature control, resulting in accurate flow rates and reproducible molar mass determinations with consistent results from run-to-run, day-to-day, and system-to-system » | The EcoSEC High Temperature GPC System has four independent heating elements that maintain a constant temperature within the range of 40 ºC to 220 ºC: pump oven, column oven, autosampler, and RI detector. Maintenance of a constant temperature of the pump heads and solvent lines of the EcoSEC High Temperature GPC System allow the pumps to deliver exactly the same flow rate under any mobile phase condition, thus improving baseline stability. Most HPLC pumps do not compensate for volume changes as a function of temperature. The autosampler in the EcoSEC High Temperature GPC System is temperature controlled by aluminum block and is independent of the pump and column oven. A stable baseline results from the temperature controlled RI detector. |

Calibration Standards
TSKgel® polystyrene bulk calibration standards are used to calibrate GPC columns for subsequent analysis of unknown samples. The standards range from 400 to 2.1 × 107 Da.
TSKgel GPC Columns
TSKgel H series GPC US | EU columns are recommended for the analysis of organic-soluble polymers and are packed with spherical particles composed of polystyrene cross-linked with divinylbenzene (PS-DVB). The TSKgel HT columns are for high temperature applications (≤ 140 °C) while the TSKgel HT2 columns are used in ultra-high temperature (up to 220 °C) applications.
The figure below demonstrates the performance stability of the TSKgel GMHHR-H HT columns compared to other commercially available high temperature GPC columns during repetitive temperature changes. The TSKgel HHR HT columns and two commercially available high temperature GPC columns were subjected to drastic changes in temperature by raising the temperature for 2 hours followed by lowering the temperature for two hours for a total of 60 cycles. The number of theoretical plates was shown to remain constant for the TSKgel HHR HT columns and to decrease by 15% for the two commercially available high temperature GPC columns; thus revealing the superior performance stability of the TSKgel HHR HT columns.
