TSKgel SuperH4000
The TSKgel SuperH4000 column is packed with rigid, porous, polymer beads. It is for the non-aqueous separation of polymers with molar masses of less than 400,000. The maximum operating temperature for the TSKgel SuperH4000 column is 140 °C. This column is shipped in THF, which can be exchanged for a wide variety of organic solvents.
This TSKgel SuperH4000 column is a high efficiency/high throughput version of the conventional TSKgel G4000HHR column. Both column types are based on the same bead chemistry. The volume of the 6 mm ID × 15 cm TSKgel SuperH4000 column is 3.4 times smaller than that of a conventional 7.8 mm ID × 30 cm column. As a result, peak volumes will be proportionally smaller on this column compared to a corresponding TSKgel HHR column. Thus, your HPLC system may require optimization of components that can give rise to extra-column band broadening, such as connecting tubing, injector, injection volume, detector cell volume, and detector time constant.
