    Lab 1 - Thin Layer Chromatography - WebAssign

    In Thin Layer Chromatography ("TLC"), a liquid solution is directly applied to a solid adsorbent. Capillary action draws a developing solvent up the TLC plate. As this solvent passes through the spot, the mixture will be dissolved and will begin to move with the solvent front. However, the adsorbent will also reabsorb part or all of the mixture.

    Thin Layer Chromatography Definition, Principles .

    Thin layer chromatography (T LC) is a chromatographic technique used to se parate the components of a mixture using a thin stationary phase supported by an inert backing. It may be performed on the analytical scale as a means of monitoring the progress of a reaction, or on the preparative scale to purify small amounts of a compound.

    One of those methods is known as thin-layer chromatography, or TLC for short. This works like all other kinds of chromatography in that you have a mobile phase and a stationary phase, and the compounds that you're trying to separate interact with these two phases. First, let's talk about the stationary phase.
