plate depending on the solvent you choose. In non-polar solvents like pentane and hexane, most polar compounds will not move, while non-polar compounds will travel some distance up the plate. In contrast, polar solvents will usually move non-polar compounds to the solvent front and push the polar compounds off of the baseline. A good solvent system is one that moves all components of your

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. As more solvent comes by, the mixture will again
