TSK-GEL GPC columns for organic-soluble polymers are packed with spherical particles composed of polystyrene crosslinked with divinylbenzene (PS-DVB). Main differences between the available product lines are highlighted in the Table below. For a detailed comparison of the product lines, including solvent compatibility, follow the link.
Tosoh redefines GPC calibration.
Tosoh's innovative multi-pore technology produces particles that contain a broad range of pore sizes. Columns with an extended linear calibration curve can now be prepared without mixing particles of different pore sizes. Visit the TSK-GEL SuperMultiporeHZ column pages to find out how multi-pore technology helps you speed up column cailibration.
TSK-GEL SuperH and TSK-GEL SuperHZ columns were developed for High-Throughput GPC applications. Both product lines feature particle sizes down to 3μm, a column length of 15cm and column diameters of 6mm ID and 4.6mm ID (SuperHZ only).
TSK-GEL Hxl and TSK-GEL Hhr columns are conventional GPC columns of 7.8mm ID x 30cm, while particles sizes are 5µm and larger for the larger pore size columns.
The benefits of TSK-GEL SuperHZ-type columns over the conventional Hxl-type columns are demonstrated in the following comparison chromatogram. Similar benefits are gained by using TSK-GEL SuperH columns over Hhr columns. |
Highlights
-
Tosoh manufactures two distinct product lines for GPC of organic-soluble polymers. While each line is based on particles prepared from polystyrene crosslinked with divinylbenzene, they differ in:
-
TSK-GEL Hxl-type, SuperHZ-type, and SuperMultiporeHZ-type columns are most inert to sample adsorption.
- TSK-GEL Hhr- and SuperH-type columns provide minimal shrinking and swelling of the column bed when changing solvents and allow operation up to 140°C.
- Small particle, narrow bore SuperMultiporeHZ, SuperHZ and SuperH columns provide high efficiency, short analysis times and operating cost.
- Except for SuperMultiporeHZ columns, all other TSK-GEL H-type column lines contain at least five different pore sizes.
- Each product line contains columns for the analysis of oligomers to polymers containing molecular weights as high as as 4 x 10^8Da (estimated).
All product lines contain a number of linear columns that are prepared by blending particles with different pore sizes. |
Table: Distinguishing features of TSK-GEL H-type GPC column lines
|
Hxl and SuperHZ |
SuperMultiporeHZ |
Hhr and SuperH |
- Ultra-low adsorption columns with limited solvent range.
- Use SuperHZ for highest resolution and throughput.
- Use Hxl if you can live with longer analyis times.
- Max. temp: 60-80°C
|
- More linear than 'linear' mixed-bed columns.
- Improved MW accuracy and precision.
- Like SuperHZ and Hxl lines in terms of surface chemistry and temp. range.
- Like SuperHZ columns in terms of resolution and speed.
|
- Low adsorption columns with expanded solvent range.
- SuperH for high throughput and high resolution GPC.
- Use Hhr if you do not have a need to save time.
- Max. temp:140°C
