WebColumn chromatography is a larger scale of thin layer chromatography. In this case, the dye mixture- a two coloured compound- was added into the column. The separation of the two different colours began as a mobile phase- mixture of 50% ethanol and 50%water- was run through the stationary phase (alumina- Al 2 O 3 ). Web10 aug. 2024 · In chemistry, thin layer chromatography (TLC) is a cheap, fast, and efficient way to separate a mixture into its components for analytical purposes. Chromatography uses a stationary phase (usually silica,alumina) and a mobile solvent phase to separate compounds. Webheld as a thin layer (or film) on the surface of an inert solid. The mixture to be separated is carried by a gas or a liquid as the mobile phase. The solutes distribute themselves between the moving and the stationary phases, with the more soluble component in the mobile phase reaching the end of the chromatography column first (Fig. 2). gsm architecture gfg
