TSKgel^® Butyl-NPR (2.5 µm) HPLC Columns

TSKgel^® Butyl-NPR columns are not as hydrophobic, i.e., less retentive, than Phenyl-5PW and Ether-5PW HIC columns. They are the best choice for high speed separations and provide excellent recovery even for more hydrophobic proteins. The non-porous resin requires lower sample loading and leads to faster analysis time because the binding kinetics occur only on the bead′s surface. The ultra efficient 2.5 micron bead allows for fast, high efficiency separations using a 3.5cm x 4.6mm ID column format. Thus, TSKgel Butyl-NPR is ideal for time critical QC analysis or sample limited applications. Featuring polymethacrylate base material, the TSKgel Butyl-NPR column is stable in either acid or caustic cleaning regimes up to 1N.
