WebChromatography has two phases, the mobile phase, where the substance is in a gaseous or liquid state. And the stationary phase, where the substance is a solid or a liquid adsorbed of the surface of a solid. Chromatography involves a specific state of equilibrium between the two phases. There are two widely used methods of chromatography, thin ... WebChromatographic separation was achieved on aluminum-backed silica gel 60F254 HPTLC plates with n -hexane-ethyl acetate 70:30 ( v / v ) as mobile phase. The method gives a compact band for racecadotril ( RF 0.59 ± 0.02) and enables excellent separation of its degradation products.
