The TSK-GEL 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. The calibration curves are shown below.

Main characteristics for SuperHZ-type columns are:
- TSK-GEL SuperHZ columns have been developed for High Throughput, High Efficiency GPC applications such as those encountered in combinatorial chemistry experiments.
- The benefits of SuperHZ columns over conventional Hxl columns are shown in the following chromatogram.
- Ultra-low sample adsorption, i.e., the columns show true size exclusion behavior for most polymers
- Maximum operating temperature for SuperHZ-type columns is 60°C for SuperHZ1000, SuperHZ2000, SuperHZ2500 and SuperHZ3000, and 80°C for the remaining columns in the product line. See 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.
Solvent compatibility for TSK-GEL SuperHZ and Hxl columns
The column shipping solvent limits the types of solvents that can be used with each column type.

Column type |
Shipping solvent* |
Can be replaced with |
|
SuperHZ and Hxl1
|
|
benzene, chloroform, toluene, xylene, dichloromethane, dichloroethane |
|
|
carbon tetrachloride4, o-dichlorobenzene, dimethylformamide, dodecane, dimethyl sulfoxide, dioxane, ethylacetate, FC-113, hexane, pyridine, hexafluoroisopropanol/chloroform, methyl ethyl ketone, quinoline, cyclohexane |
|
|
m-cresol in chloroform, up to 10% hexafluoroisopropanol/chloroform |
|
|
dimethyl sulfoxide, dioxane, tetrahydrofuran, toluene |
|
|

Notes:
1) In case of SuperHZ and Hxl, keep flow rate below <0.5mL/min during solvent change. Solvent can be changed one way/one time only.
2) All TSK-GEL Hxl, Hhr, SuperHZ and SuperH analytical columns are shipped containing tetrahydrofuran (THF), except High Temperature (HT) columns, which contain o-dichlorobenzene.
3) THF in G1000Hxl columns cannot be replaced with dichloromethane or dichloroethane.
4) Prolonged exposure to carbon tetrachloride can corrode the stainless steel parts of a column and an HPLC system.
* 100% methanol cannot be used with H-type columns; use this solvent with TSK-GEL SW-type or Alpha-type columns.
** TSK-GEL H columns may be specially ordered with this shipping solvent.

Beware of extra-column bandbroadening
Column dimensions are 6mm ID x 15cm and 4.6mmID x 15cm versus 7.8mm ID x 30cm for conventional GPC columns. The smaller column dimensions translate to a reduction of peak volume by a factor of 3.4 (6mm ID) and a factor of 5.8 (4.6mm ID) versus the same component eluting from a corresponding 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.
Columns with linear calibration curves
The TSK-GEL SuperHZ product line contains three 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 SuperHZM-L, SuperHZM-N, SuperHZM-H.
