Abstract
Methods of conducting Thin Layer Chromatography (TLC) involving using a TLC plate having sample spots and including no support material, placing the TLC plate on a porous substrate, and allowing solvent to move upwardly from the porous substrate toward the TLC plate by capillary action to be vaporized from the surface of the TLC plate, thereby concentrating the sample spots developed in the thin layer on the surface of the TLC plate.
