Tosoh TSKgel GMHhr-N Mixed Bed GPC Column, 5 µm, ID 7.8 mm x L 30 cm - 18055

Main characteristics

• Maximum operating temperature for TSKgel Hhr-type columns is 140°C.
• Broad solvent range. All TSKgel Hhr-type columns are shipped in THF, which can be exchanged for a wide variety of organic solvents as shown below.
• TSKgel Hhr-type columns are conventional GPC columns with dimensions of 7.8 mm ID x 30 cm L. Most HPLC systems do not require optimization of extra-column bandbroadening effects when working with conventional GPC columns.

Columns with linear calibration curves

The TSKgel Hhr product line contains five linear, or mixed-bed columns, in which particles with different pore sizes are blended to provide an extended linear calibration curve. The mixed-bed columns feature increasing linear calibration ranges, from TSKgel GMHhr-L, GMHhr-N, GMHhr-M, to GMHhr-H. TSKgel GMHhr-H(S) HT is a high temeperature mixed bed column shipped in ODCB, o-dichlorobenzene. 

TSKgel GMHhr-N mixed bed columns are packed with rigid, multiple pore size, polymer beads. Mixed bed columns are commonly used for unknown samples and for the analysis of polymers with a broad molecular weight distribution. TSKgel GMHhr-N columns are shipped in THF, which can be exchanged for a wide variety of  organic solvents.
