Gel permeation chromatography / size exclusion chromatography (GPC/SEC) is a well known technique for the separation of macromolecules like natural and synthetic polymers. It is the method of choice for the characterization of polymer molecular weight and molecular weight distribution.
Tosoh Bioscience is a leading manufacturer of SEC/GPC columns and developed GPC instruments for the Asian market for more than 20 years.
EcoSEC is the 7th generation of Tosoh GPC system engineering. It is a compact, all-in-one system with refractive index detection for fast, high resolution, semi-micro GPC at temperatures below 60°C. It comprises a dual pump precision solvent delivery system, an automatic injector, a column oven and a high performance dual flow refractive index detector as standard.
EcoSEC can be equipped with additional detectors like UV, light scattering and viscosity detectors.
The EcoSEC GPC system is engineered to minimize extra column dead volume. This permits the use of smaller columns such as the TSK-GEL SuperMultiporeHZ semi- micro GPC columns. These columns are 4.6 mm ID x 15 cm L and consume about one sixth of the solvent compared to conventional systems and columns. In addition, run times are often half that of larger columns. At the same time semi-micro GPC often improves resolution and signal to noise levels.
