Functionalized silicas as core supports for chiral stationary phases

A chiral stationary phase represented by T--O--Si--U, where T is a refractory inorganic oxide with a surface of at least 35 m.sup.2 per gram and having bound surface hydroxyl groups, O--Si is a covalent bond between said bound surface hydroxyl groups and the silicon atom of a silane, and U is a polyamine selected from the group consisting of polyamines with the formula ##STR2## and ##STR3## where x is an integer from 1 up to about 10, y is an integer from 2 to 4, A, B, D and E are selected from the group consisting of hydrogen and lower alkyl containing from 1 up through 4 carbon atoms, and p, q, and r are integers from 1 up through about 10, said polyamine further comprising an adsorbed or covalently bonded chiral organic material.
