The TSK-GEL (SEC) columns include both types of molecular exclusion chromatography: GFC or Gel Filtration Chromatography for the separation of water soluble polymers, and GPC (Gel Permeation Chromatography) for polymeric compounds soluble in organic solvents.
TSK-GEL SW;TSK-GEL SWXL and TSK-GEL Super SW for the analysis of peptides and proteins by Gel Filtration Chromatography.
The silica based TSK columns are the best choice for the separation by molecular size of peptides and proteins thanks to their high efficiency, low adsorption, and their well defined and controlled distribution of pore size.
The SW columns, of 10μm particle size, have been the most popular since their introduction in the year 1978, and now constitute a market standard. The SWXL are improved on the earlier ones, due to their particle size of 5 microns, which, while maintaining efficiency, cuts analysis time by half. Finally, the columns SuperSW, with 4 micron particles of high efficiency, allows operation with columns of 4.6 mm I.D., acheiving a spectacular increase of efficiency and detection sensitivity.
