CHEM 344 Thin Layer Chromatography
www2.chem.wisc.educonsists of a volatile organic solvent or mixture of solvents. A solution of the sample containing a mixture of compounds is applied to the layer of adsorbent, near one edge, as a small spot. The TLC plate is propped vertically in a closed container (developing chamber), with the edge to which the spot was applied down. The solvent, which
