    Ion - Exchange Chromatography - Vanderbilt University

    In cation-exchange chromatography, the stationary phase, which consists of a large quantity of acid groups attached to a polymeric resin, is slurried with water and applied to a column. The mobile phase, which contains the inorganic salt dissolved in a suitable solvent, is applied to the column.

    At the extreme, air in the pump will cause the pump to stop delivering mobile phase to the column. If only an occasional bubble is present, the flow rate will be erratic, causing retention time problems. Air in an optical detector, such as an ultraviolet (UV), fluorescence, or refractive index detector,...

    column can be used as a convenient solvent reservoir. Fig. 7.2 Preparation of a chromatography column. Note that the silica gel is packed into the column as a dry powder. The column is prepared in the following manner: 1. With a long wire (a straightened coathanger works well), tamp a small wad of glass wool into the bottom of the column.

    Measuring Column Flow and Velocitytech

    The column velocity, or more precisely the carrier-gas linear velocity through the column, tells chromatographers how quickly the chromatography will take place and how efficiently a column can resolve the peaks, given no external interference. Operating close to optimum velocity provides a compromise between speed of analysis and column efficiency.
