MULTIMODAL ANION EXCHANGE MATRICES

摘要

The invention discloses a separation matrix which comprises a plurality of separation ligands, defined by the formula Ri- Li- N (R3 ) - L2- R, immobilized on a support, wherein Ri is a five- or -six membered , substituted or non- substituted ring structure or a hydroxyethyl or hydroxypropyl group; Li is either a methylene group or a covalent bond; R2 is a five -or- six membered ,substituted or non- substituted ring structure; L 2is either a methylene group or a covalent bond;R3 is a methyl group; and wherein if Ri is a hydroxyethyl group and Li is a covalent bond , R2 is a substituted aromatic ring structure or a substituted or non- substituted aliphatic ring structure.
