General description

TSKgel Ultra-High Temperature columns are for the analysis of organic-soluble polymers at extremely elevated temperatures. These columns are for applications up to 220°C and are shipped in o-dichlorobenzene (ODCB), which can be exchanged for 1-chloronaphthalene and trichlorobenzene.
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.

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.

Physical form

ODCB can be exchanged by 1-chloronaphthalene and trichlorobenzene.
