The Thin-Layer Chromatography Puzzle: Cracking the Code - api

TLC is a separation technique that relies on the interaction between a stationary phase and a mobile phase to separate components of a mixture. In a typical TLC setup, a sample is applied to a plate coated with a thin layer of a stationary phase, usually silica or alumina. A mobile phase, such as a solvent or mixture of solvents, is then passed over the plate, causing the components to separate based on their affinities for the stationary and mobile phases. This results in a distinctive pattern of spots on the plate, which can be analyzed to identify the individual components.
