  • What is Column Chromatography ? A Beginners guide

    The instrument consists of a column and a stand. The column chromatography contains a vertical column made of neutral glass with a knob at the bottom end. Glass column is chosen so to avoid reactions with solvents, acids, and alkalies. The surface of the cylindrical column is clear without graduations or readings on the surface.

    In 1978, W.C.Still introduced a modified version of column chromatography called flash column chromatography [15] [16]. The technique is very similar to the traditional column chromatography, except for that the solvent is driven through the column by applying positive pressure. This allowed most separations to be performed in less than 20 minutes,

  • Separating Compounds by Column Chromatography

    Separating Compounds by Column Chromatography Column chromatography is similar to TLC in that a mixture of compounds can be separated by being carried by a mobile phase through a stationary phase. However, instead of just giving us information about the mixture, column chromatography is used to actually separate larger amounts of the compounds.
