Column chromatography examples

WebChromatography is a separation process involving two phases, one stationary and the other mobile. Typically, the stationary phase is a porous solid (e.g., glass, silica, or alumina) that is packed into a glass or metal tube or that constitutes the walls of an open-tube capillary. The mobile phase flows through the packed bed or column. WebMar 9, 2003 · An example of a RPC system is a C18 column (i.e. packed with porous silica with a bonded layer of octadecyl hydrocarbon chains) in combination with a gradient decreasing in polarity. According to experience, nonexclusion HPLC of synthetic polymers usually requires gradient elution. 8 Water is a very popular eluent component in low …
