Increased Resolution and Reproducibility with TSKgel® UP-SW3000 Columns Versus a Competitive Column
TSKgel UP-SW3000 columns are 2 µm SEC columns designed for the analysis of monoclonal antibodies and other biopharma products. Higher resolution can be achieved for the separation of antibody monomers, dimers, and higher order aggregates with a TSKgel UP-SW3000 column compared to a competitor UHPLC column. The TSKgel UP-SW3000 column provided excellent reproducibility for the peak parameters of retention time, asymmetry, and column efficiency. As demonstrated by the %RSD values, injection-to-injection reproducibility was superior to the competitor column.
