Abstract

A chromatography column for the use of separation of acidic sugar chains, wherein the column comprises a first column and a second column, the second column connected by a flow path downstream of an outlet of the first column, and selected from the following (1) or (2): (1) the carrier of the first column is hydrophobically modified silica having a group containing a primary amine, a secondary amine or/and a tertiary amine, and the carrier of the second column is a resin having a group containing a primary amine, a secondary amine or/and a tertiary amine; (2) the carrier of the first column is a resin having a group containing a primary amine, a secondary amine or/and a tertiary amine, and the carrier of the second column is hydrophobically modified silica having a group containing a primary amine, a secondary amine, or/and a tertiary amine.
