TSK-GEL SEC Columns for Size Exclusion Chromatography (SEC)

Gel filtration – Size Exclusion Chromatography with aqueous eluents is a very popular method of analysis for proteins. Tosoh Bioscience is a world leader in the area of SEC columns based on silica- and polymer based columns. Since its introduction of the first generation of TSK-GEL SW HPLC columns almost 30 years ago, TSK-GEL columns are leading the way in the separation of proteins and other biopolymers with SEC. By further developing the columns, Tosoh Bioscience continually extended SEC portfolio. It comprises:

- silica based TSK-GEL SW columns
- TSK-GEL PW polymer columns
- Alpha and SuperAW columns for SEC with aqueous and organic mobile phases

The TSK-GEL SEC brochure comprises all aspects of SEC, starting with the basics, tipps for application of the SEC columns, and application examples for the different column types.

TSKgel SuperSW columns deliver a specifically high resolution and sensitivity and they are the latest development of the SW technology. The higher separation ability was reached by reducing the inner diameters of the columns and the application of smaller particles (4 µm). The columns are specifically suitable for SEC analysis, that require high sensitivity. Typical areas of application are in biotechnology, proteomics, or quality control of biopharmaceutica.

The TSK-GEL SuperSW brochure delivers a comprehensive overview of high resolution SEC. Aside from the basics of gel filtration and applications, the brochure contains recommendations for method development, care of the columns and necessary optimization of HPLC systems.
