The stationary phase in TLC is usually an adsorbent (Table 1) composed of very fine and highly porous particles coated as a thin layer onto a support. Today, the most widely used stationary phase is silica gel 60. With a solvent or solvent mixture as mobile phase, a liquid-solid chromatographic system is formed. Separation of sample components can be primarily described as adsorption chromatography. Sample molecules are retained due to specific interaction on the surface of the stationary phase while... 

A homogeneous chemical substance, for example an element such as sulphur or a compound such as water, may exist in several, and must be capable of existing in at least three different forms, viz. as gas, as liquid, and as solid. In many cases the solid may exist in various allotropic modifications, which differ from one another in crystalline form, melting point, density, specific heat, and, in fact, in all their ph5rsical properties. Every portion of matter which is in itself homogeneous, i.e. in which the smallest visible particles are exactly alike, and which is therefore separated in space from every other homogeneous but dissimilar portion of matter, was called by Willard Gibbs a phase. ...
