PURPOSE: To obtain a packing material which provides a wide range of applicable compd., is chemically stable, and is suitable for spen. and analysis of an enantiomorphic mixture having a specific group, by grafting an optically active S-triazine deriv. having an asymmetric carbon atom onto an inorg. carrier having an OH group on the surface.

CONSTITUTION: A chromatograph packing material is manufactured by grafting the compd. having ≥1 asymmetric carbon atom expressed by the formula I (R1, R2 and R3 are alkyl, alkoxy, OH or halogen, ≥1 among R1WR3 are alkoxy or halogen and m, n are 2, 3 or 4, X, Y are the residual group of an optically active amine or alcohol), for example, having the optically active S-triazine deriv. expressed by the formula II with an inorg. carrier such as silica gel having an OH group on the surface. An enantiomorphic mixture of compd. having -CONH-, -CO-, -OCONH group, etc. is made separable and analyzable in a short time with high efficiency by using such packing material.
