Abstract
Provided is a separation method for amine, the separation method including performing liquid chromatography, wherein a separating agent in which a ligand having a crown ether-like cyclic structure is supported on a carrier is used as a stationary phase, and wherein a mobile phase contains an aqueous solution of at least one salt of a hydrophobic anion selected from the group consisting of a salt of a chaotropic anion and a salt of a hydrophobic organic acid.
