Abstract: Provided is a stationary phase for supercritical fluid chromatography, the stationary phase having satisfactory molecule-identifying ability, in particular, satisfactory separating properties with respect to not only acidic compounds or basic compounds but also fused aromatic compounds or aromatic isomers. The stationary phase for supercritical fluid chromatography includes a support having, bonded thereto, a polymer in which the main chain has nitrogenous aromatic rings in the repeating units.
