General description
Diaion® HP-2MG is a methacrylic ester copolymer which is hydrophilic in nature. It is widely used for preconcentration and separation of traces of heavy metal ions. It is also used as adsorbent for polyphenols and surfactants.[1]
Application
Aliphatic adsorbent for moderately polar compounds, such as: antibiotics, color bodies, and aliphatic analytes. The resin exhibits broad spectrum adsorption of small and large molecules.
Other Notes
Swelling in toluene = 5%
