What does TLC stand for?

• A. Thin Layer Chromatography
• B. Thin Layer Centrifugation
• C. Thin Layer Crystallography
• D. Time Layer Chromatography

Answer: (A)

Thin Layer Chromatography is an acronym where each word describes a part of the method: the separation happens on a plate coated with a very thin layer of adsorbent, like silica gel or alumina, and the technique relies on the flow of a solvent (the mobile phase) up the plate to separate components by their different affinities to the stationary layer versus the moving solvent. This is what the term TLC is shorthand for. The other options don’t fit: centrifugation uses spinning to separate components and isn’t chromatography; crystallography deals with crystal structures; there isn’t a standard method known as Time Layer Chromatography.
