HPLC Column Sepax TweenTrap, 5 µm, 7.8 x 50 mm

The Sepax TweenTrap column is specifically designed for trapping surfactants, such as Polysorbate 80/20 (PS 80/20, Tween 80/20), in aqueous samples. The packing support is composed of rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) beads with a particle size of 5 ?m and a proprietary surface coating is covalently bonded onto the PS/DVB support. TweenTrap columns can be run in tandem with SEC columns in aqueous samples, and are specifically designed to trap and remove surfactants, such as Polysorbate 80/20, which can interfere with quantitative protein SEC analysis.
