TweenTrap columns are specially designed for trapping surfactants, such as Tweens, in aqueous samples. Their packing support is composed of rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) beads with a particle size of 5 µm. A proprietary surface coating is covalently bonded onto this PS/DVB support, which allows for exceptionally high stability. These columns are compatible with most aqueous buffers such as acetate, phosphate, and tris.
Highly cross-linked PS/DVB resin support grafted with a densely packed, nanometer thick amphiphilic coating.
