Experiment 1: Thin Layer Chromatography • Chromatography: Separation of a mixture into components by distribution between a mobile (solid or gas) phase and a stationary (liquid) phase. • Separations are based by physical interactions (solubility, polarity, s ize, charge, etc.). • In TLC, the stationary phase is a finely divided solid (silica gel SiO2or alumina Al 2 )3on an inert support such as glass or sheet of plastic/aluminum. The mobile phase solvent is allowed to move up TLC plate by capillarity. • The rate at which components move along the path depends upon their solubility in the mobile phase, and the strength with which molecules of the different substances are adsorbed on the surface of the stationary
