Desalting RP columns are specifically designed for removing salts from aqueous biomolecule samples such as peptides, proteins and DNAs while enabling online MS analyses of the biomolecules. The packing support is composed of porous, spherical, and highly cross-linked poly(styrene/divinylbenzene) (PS/DVB) beads with a particle size of 5 μm. The column is compatible with most aqueous buffers, such as acetate, phosphate, tris, etc.
Sepax Desalting RP columns come in a combo pack containing 3 columns and one holder.
Highly cross-linked PS/DVB resin support grafted with a densely packed, nanometer thick amphiphilic coating.
