WebThe current state of chiral separations by thin-layer chromatography using chiral stationary phases is reviewed. Both stationary phases essentially constituted by the chiral selector and those obtained by the impregnation of achiral plates with appropriate chiral selectors are described. WebScientists use the analytical technique of Thin Layer Chromatography, known as TLC, to separate compounds. The TLC process involves spotting a TLC plate with a compound in order to isolate and identify its constituents and check reaction progress.
