In thin layer chromatography some form of optimization is generally necessary if complete separation of all components in a sample is required and if the number of these is larger than a small fraction of the spot capacity of the system. The selection of the solvent system is one of the ...
TLC, or Thin-Layer Chromatography, is a commonly used technique in synthetic chemistry to check for purity and the progress of reactions.TLC uses a stationary phase, typically a silica gel bound to a plastic, glass or aluminum backing, and a mobile phase, typically common organic solvents such...
Thin layer chromatography (TLC) is a widely used analytical technique in many industries, including the pharmaceutical, cosmetic, food, and environmental sectors. It involves the separation of a mixture of compounds based on their different affinitiesfor a stationary and a mobile phase. The stationary...
In column chromatography a defined sample amount is injected into a flowing mobile phase. The mix of sample and mobile phase then migrates through the column. If the separation conditions are arranged such that the migration rate of the sample components is different then a separation is obtained...

You have already had some experience with gas chromatography where the mobile phase is an inert gas, usually helium, and the stationary phase is a high boiling liquid coating absorbed on the surface of a granular solid in a column. In thin layer chromatography, or TLC, the mobile phase is ...
