TSKgel SuperHZM-N

TSKgelSuperHZM-N

TSKgelSuperHZM-N mixed bed GPC columns are packed with rigid, multiple pore size, polymer beads that are blended to provide an extended linear calibration curve. Mixed bed columns are commonly used for unknown samples and for the analysis of polymers with a broad molecular weight distribution. These columns provide high resolution of polymers with molar masses of less than 700,000 Da. The maximum operating temperature for the TSKgel SuperHZM-N columns are 80 °C. The THF shipping solvent may be replaced by a limited number of organic solvents.

TSKgel SuperHZM-N column dimensions are 6 mm ID × 15 cm and 4.6 mm ID × 15 cm versus 7.8 mm ID × 30 cm for conventional GPC columns. The smaller column dimensions translate to a reduction of peak volume by a factor of 3.4 (6 mm ID) and a factor of 5.8 (4.6 mm ID) versus the same component eluting from a corresponding TSKgel HXL 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.
