www2.chem.wisc.eduTLC, one phase is a mobile liquid solvent phase and the other phase is a stationary solid phase with a high surface area. The stationary phase normally consists of a finely divided adsorbent, silica (SiO 2) or alumina (Al 2O 3) powder, used in the form of a thin layer (about 0.25 mm thick) on a supporting material.

In Tsvet’s experiment, the stationary phase was the calcium carbonate and the mobile phase was the organic solvent.
