EcoSEC® HT GPC System

EcoSECHT400px.jpg

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 features:

  • Reliability
  • Reproducibility
  • Stability
  • Safety
  • All-in-one design
  • Ease of use

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® H series GPC 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.
