Gel Permeation Chromatography

TSKgel GMHhr-H(S) HT Mixed Bed GPC Guard Column, 30 µm, ID 7.5 mm x L 7.5 cm

The TSKgel Hhr column line consists of eight columns with different pore sizes, TSKgel G1000Hhr through TSKgel G7000Hhr, and five columns with an extended linear range of the calibration curve.

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-H(S) HT mixed bed columns are packed with rigid, 13 μm, polymer beads of various pore sizes. They are used for the high temperature analysis of very large polymers having a broad molecular weight range where shear forces need to be minimized. TSKgel GMHhr-H(S) HT columns are shipped in o-dichlorobenzene (ODCB).
