TSKgel 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 TSKgel SuperMultiporeHZ column pages to find out how multi-pore technology helps you speed up column cailibration.
TSKgel SuperH and TSKgel SuperHZ columns were developed for High-Throughput GPC applications. Both product lines feature particle sizes down to 3 μm, a column length of 15 cm and column diameters of 6mm ID and 4.6 mm ID (TSKgelSuperHZ only).
TSKgel Hxl and TSKgel Hhr columns are conventional GPC columns of 7.8 mm ID x 30 cm L, while particles sizes are 5 µm and larger for the larger pore size columns.
The benefits of TSKgel SuperHZ-type columns over the conventional Hxl-type columns are demonstrated in the following comparison chromatogram. Similar benefits are gained by using TSKgel SuperH columns over Hhr columns.
