TLGC can be carried out only when the pores of the gel materials are filled with the eluent solvent, so that this method requires a number of special experimental techniques different from the usual thin-layer chromatography. This review describes an essential peculiarity of TLGC and the experimental techniques involved, and emphasizes recent applications of TLGC to lypophilic substances and inorganic substances, although most of the published applications are concerned with biological materials. 225Brought to you by | Purdue University Librarie Authenticated Download Date | 7/2/15 10:16 AM
