Ion Exchange Column Diagram

The hardness ions ca and mg move into the resin beads and each of these divalent.

Ion exchange column diagram. Ion exchange ix systems are used across a variety of industries for water softening purification and separation purposes. The ion exchange column has a solid resin feed of 10 m 3 h and an interstitial liquid factor of 0 85. While the chemistry of individual ion exchange reactions varies from one application to the next ix is a treatment process where dissolved ions are replaced by other more desirable ions of a similar electrical charge. The interstitial liquid fed with the resin contains caustic soda and the liquor flow corresponds to one bed volume.

Ion exchange chromatography workflow. Ion exchange chromatography can be applied to the determination of ionic solutes such as inorganic anions cations transition metals and low molecular weight organic acids. Thus the workflow below is given as a generalized iex workflow and particular running conditions for cation exchange chromatography may be adjusted to best suit your protein of interest the buffer system and the anion. The table below shows the material flows in m 3 h around the ion exchange column.

They are well suited for processing feedwater for medium pressure boilers and for process water for the beverage industry. Ion exchange dealkalization systems produce hardness free low alkalinity water at a reasonable cost and with a high degree of reliability. Key steps in the ion exchange chromatography procedure are listed below. Rohm and haas ion exchange ion exchange introduction 4 fd sep 2008 to soften water you take a cation exchange resin on which the mobile ion inside the beads is sodium na and you pass the hard water through a column filled with the sodium form resin.

Aside from its use to purify drinking water the technique is widely applied for purification and separation of a variety of industrially and medicinally. A separation column and a detector to measure the species eluted from the column. For example metal contaminants are undesirable due to their color taste odor or toxicity. Usage examples continuous ion exchangers are used when it is imperative that product be continually generated.

Cation exchange chromatography workflow. Schematic diagram of the principles of chromatography as discovered by tswett 1901. Split stream and weak acid cation systems also reduce the total dissolved solids. An impure protein sample is loaded into the ion exchange chromatography column at a particular ph.

All ion exchange chromatography relies on electrostatic interactions between the resin functional groups and proteins of interest.
