TSKgel GPC Columns
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 GMH
HR-H HT columns compared to other commercially available high temperature GPC columns during repetitive temperature changes. The TSKgel H
HR 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 H
HR 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 H
HR HT columns.
