Liquid-Solid (Absorption) Chromatography
Liquid-Solid (Absorption) Chromatography :
The liquid mobile phase (ie mixture A and B) is passed through a column packed with silica gel or alumina. Liquid - Liquid (Partition) Chromatography. The mobile phase is passed over a thin layer of liquid held on the surface of a porous inert solid such as paper in water. The process is sometimes known as 'thin layer' or 'paper' chromatography. High Pressure Liquid Chromatography (HPLC). Separation is achieved by reducing the particle size of the stationary phase and forcing the mixture through at high pressure, hence HPLC
