Description
Sepax SRT SEC columns feature a hydrophilic surface layer that effectively shields the highly porous, five micron silica particles from interacting with your sample. SRT columns are employed in the quality control of biotherapeutics by gel filtration chromatography. Select from a wide variety of available pore sizes to analyze peptides, proteins, glycoproteins, vaccines and water soluble polymers. Swelling (dry to solvent saturated, %): hexane 10-15; toluene 10-15; ethylene dichloride 15-20; ethylene acetate 30-40; 95% ethylene alcohol 60-70; water 60-70.Strongly acidic cation exchange resin used as a heterogeneous acid catalysis; suitable for non-aqueous catalysis. Strongly acidic, macroreticular resin with sulfonic acid functionality which is suitable for non-aqueous catalysis
