TSKgel GMHhr-H (S) HT2

The TSKgel GMHhr-H (S) HT2 ultra-high temperature mixed bed column is packed with rigid 13 µm polymer beads and is for the analysis of organic-soluble polymers at extremely elevated temperatures. This column is for applications up to 220 °C and is shipped in o-dichlorobenzene (ODCB), which can be exchanged for 1-chloronaphthalene and trichlorobenzene. The issue of shearing that occurs with the analysis of ultra-high molar mass polymers is overcome by the TSKgel GMHhr-H (S) HT2 column. The (S) is a reference to this shearing effect. 

The TSKgel mixed bed columns are packed with particles of different pore sizes that are blended to provide an extended linear calibration curve. Mixed bed columns are used when a broad range of polymer molar masses is expected in the sample.
