Diaion HP20
Diaion HP20 synthetic adsorbent resin is a macroporous styrenic polymeric bead type resin designed for adsorption/desorption process scale applications. Its matrix provides an aromatic non-polar surface with excellent selectivity for hydrophobic areas of molecules, including biomolecules like antibiotics via low energy van der Waal's interactions. It is remarkable for its wide pore polymeric structure which provides excellent broad spectrum adsorption characteristics. Diaion HP21 has slightly smaller pores, and slightly higher surface area than Diaion HP20.
The Sepabeads SP825L and SP850 resins
The Sepabeads SP825L and SP850 resins provide a smaller more uniform pore size distribution and higher surface area as compared to Diaion HP20. The increase in surface area is approximately 2x traditional adsorbents, and nearly matches the surface area of activated carbon. In many applications, this means twice the working capacity for the same volume of resin. They are recommended for industrial chemical process applications, bio/pharmaceutical applications such as desalting and extraction, and waste treatment…
