Abstract
A highly selective bonded phase material useful to separate a wide variety of organic and inorganic substances by thin layer chromatography (TLC), liquid chromatography (LC) or high performance liquid chromatography (HPLC) is produced by bonding a cyclodextrin to a silica gel by means of a specific silane linkage. The preparation of such materials and their uses are described.
