WebSpi(τ-dec) was successfully employed in the past to prepare home-made chiral columns for chiral ligand-exchange high-performance liquid chromatography. In the present article a new method is described, using Spi(τ-dec) as a chiral selector in high-performance thin-layer chromatography (HPTLC): commercial hydrophobic plates were first coated ... 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.
