WebIn addition, reverse-phase TLC plates also separate by partition chromatography. TLC plates are also available precoated with reverse-phase silica gel that has been impregnated with a chiral reagent and copper ions. These can be used to separate optically active isomers, e.g., amino acids, by chiral chromatography on the basis of ligand exchange.
