Product Number: 19660

Specifications:

• Matrix:    polystyrene-divinylbenzene 
• Particle size (mean):    3 µm

• Max. temp:    80 °C
• Shipping solvent:    THF 

TSKgel SuperHZM-N mixed bed 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 molecular weights 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.

Gel Permeation Chromatography

The TSKgel SuperHZ column line consists of five columns with different pore sizes, TSKgel SuperHZ1000 through TSKgel SuperHZ4000, and three columns with an extended linear range of the calibration curve, TSKgel SuperHZM-N, TSKgel SuperHZM-M and TSKgel SuperHZM-H. 

Main characteristics for SuperHZ-type columns are:

• TSKgel SuperHZ columns have been developed for High Throughput, High Efficiency GPC applications such as those encountered in combinatorial chemistry experiments.
• Ultra-low sample adsorption, i.e., the columns show true size exclusion behavior for most polymers
• Maximum operating temperature for TSKgel SuperHZ-type columns is 60°C for TSKgel SuperHZ1000, SuperHZ2000, SuperHZ2500 and SuperHZ3000, and 80°C for the remaining columns in the product line. See TSKgel SuperH-type columns for operating temperatures of 140°C.
• Limited solvent range. The columns are shipped in THF, which can be exchanged for a limited number of organic solvents as shown below.
• Beware of extra-column bandbroadening

Column dimensions are 6 mm ID x 15 cm L and 4.6 mm ID x 15 cm L versus 7.8 mm ID x 30 cm L 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 bandbroadening, such as connecting tubing, injector, injection volume, detector cell volume, and detector time constant.

TSKgel SuperHZM-N mixed-bed columns are packed with rigid, porous, polymer beads each having a varying mean pore diameter. They are used for the analysis of organic-soluble polymers with high molecular weights of less than 700,000 Da. The THF shipping solvent may be replaced by a limited number of organic solvents.
