Hydrophilic anion exchange chromatography media |
| abstract |
The anion exchange stationary phase includes a matrix particle, a base polycondensation layer attached to the matrix particle, one or more alkylamine polycondensation layers covalently attached to the base polycondensation layer, and a terminating polycondensation layer covalently attached to the alkylamine polycondensation layer. Their layers are formed from an amine and polyethylene oxide, wherein the hydroxyl group is separated from the amine by two carbon atoms. |
