TSKgel UP-SW2000 columns are designed for the analysis of small proteins, peptides and oligonucleotides. The columns are packed with 2 μm silica-based beads shielded with a hydrophilic diol-type bonded phase that prevents the silica surface from interacting with protein samples.
TSKgel UP-SW2000 columns feature the same pore size as the well-established TSKgel SuperSW2000 columns. Hence methods developed using TSKgel SuperSW2000 columns can easily be transferred to TSKgel UP-SW2000 columns on conventional HPLC systems as well as on UHPLC systems.
TSKgel UP-SW2000 columns offer higher resolution, improved peak shape and increased efficiency yielding methods that are robust, reproducible and easily transferrable between UHPLC and HPLC systems.
TSKgel UP-SW2000 columns offer superior reproducibility injection-to-injection, from column-to-column within the same lot and from lot-to-lot. %RSD values for peak parameters including retention times, area peak height, peak asymmetry, and theoretical plate count demonstrate the exceptional reproducibility of these columns.
