Abstract
The present invention is directed to inorganic oxide particles that have been modified with a chelator group. In an embodiment, the chelator group is covalently bonded to a polymer. In an embodiment, the chelator group is covalently bonded to a chiral selector ligand. The present invention is also directed to methods of modifying inorganic oxide particles with a chelator group.
Claims18
A particle for use in chromatography columns comprising:
- an inorganic oxide core,
- a cross-linked polymer coating surrounding the inorganic oxide core, and
- a chelator bonding the cross-linked polymer to the inorganic oxide core, the chelator covalently bonded to the cross-linked polymer.
