Q polystyrene-divinylbenzene(PS/DVB) resin

• Cat.No.: quaternary amine-010P
• Product Overview: Q polystyrene-divinylbenzene(PS/DVB) resin is an ion exchange packing. The highly cross-linked porous polystyrene/divinylbenzene (PS/DVB) monodisperse microspheres are used as the matrix to ensure good rigidity and polar back pressure, reducing the cost of equipment. The unique bonding technology bonds a hydrophilic layer with extremely high chemical stability on the surface of the microspheres, which eliminates the non-specific adsorption of biomolecules by the matrix, and ensures its good separation efficiency and biological sample recovery rate. Coupled with good surface functionalization technology, the product has great
  Chemical and physical stability of chromatography media with other matrix types.
