silica gel plate and the development solvent for the spotted material. The very polar silica gel tries to hold the spot in its original place and the solvent tries to move the spot along with it as it travels up the plate. The outcome depends upon a balance among three polarities - that of the plate, the development solvent and the spot material.

The particle size distribution used for the silica is related to the nature of the plate. For standard TLC, silica gel with a mean particle size of 10 - 14 µm is used compared to HPTLC where a smaller particle size is required. In both cases, pore diameter is always 60 Å. Some functionalized silica gels like reversed-phase ( C18, C8, Amine ...
Silica Gel 60 plates (Merck No. 5626, 0.25 mm thickness, 10 cm×20 cm) are most often used.
