PURPOSE:To improve the separation capacity of a mirror-image compound mixture to analyze the same rapidly, by using a packing material obtained by grafting an inorg. carrier having a OH group on the surface thereof with a compound formed by bonding aminoalkylsilane to optically active isocyanate or a derivative thereof. CONSTITUTION:A compound shown by a formula I [wherein R1, R2, R3 are alkyl, alkoxy, OH or halogen and at least one or more among R1-R3 is alkoxy or halogen, X is -NH-, -NHCO-(CH2)m-NH-N<+>H3 or divalent groups shown by formulae II, III, m is 1-5, R5 is aryl, alkyl or aralkyl, Ar is (substituted) phenyl or naphtyl. Herein, when Ar is naphtlyl, R4 is CH3, n is 2-4 and * is asymmetric carbon] is bonded to an inorg. carrier having a OH group on the surface thereof such as silica to obtain a chromatograph packing material. This packing material is easy to prepare, has a chemically stable wide application range and enables the separation and quantitative analysis of a mirro-image compound mixture in good separation capacity within a short time. |
