Cevap
The correct answer is d) None of the above.Thin-layer chromatography (TLC) is a type of chromatography that involves the separation of components in a mixture based on their differential migration on a thin layer of a stationary phase, typically a polar substance such as silica gel or cellulose. The mobile phase, which is a solvent or a mixture of solvents, moves through the stationary phase by capillary action or under the influence of an external force, such as gravity or an electric field. The components in the mixture are separated based on their differential affinity for the stationary phase and their differential solubility in the mobile phase. TLC is commonly used in analytical chemistry for the identification and quantification of compounds in a mixture.
