Column chromatography is a separation technique in which the stationary bed is within a tube. The particles of the solid stationary phase or the support coated with a liquid stationary phase may fill the whole inside volume of the tube (packed column) or be concentrated on or along the inside tube wall leaving an open, unrestricted path for the mobile phase in the middle part of the tube (ope… WebbThin-layer chromatography is performed on a sheet of an inert substrate such as glass, plastic, or aluminium foil, which is coated with a thin layer of adsorbent material, usually silica gel, aluminium oxide (alumina), or cellulose. This layer of adsorbent is known as the stationary phase.

WebbThin Layer Chromatography is a solid-liquid technique in which the two phases are a solid or stationary phase and a liquid or moving phase. The most commonly used solid phases in chromatography are silica gel and alumina. The solid phase materials are also called adsorbents due to their physical properties.
