Abstract

The amine separation method comprises a separation step for separating amine by chromatography using a stationary phase that contains at least any of an oligosaccharide, a polysaccharide, and derivatives thereof, and using a mobile phase that contains a solvent, at least one base, and at least one prescribed acid selected from the group consisting of oxalic acid, acetic acid, formic acid, and trifluoroacetic acid. SB/SA in this amine separation method is at least 0.05 and not more than 0.95, where A is the value calculated using formula (1) for each prescribed acid present in the mobile phase, SA is the total value of the individual As calculated for the individual prescribed acids, B is the value calculated using formula (2) for the base present in the mobile phase, and SB is the total value of the individual Bs calculated for the individual bases. Formula (1): A = valence of the prescribed acid × molar concentration of the prescribed acid (mol/L); Formula (2): B = valence of the base × molar concentration of the base (mol/L)
