What is principle of ion exchange chromatography? The molecules separated on the basis of their charge are eluted using a solution of varying ionic strength. By passing such a solution through the column, highly selective separation of molecules according to their different charges takes place.
What is the mechanism of ion exchange process? Ion exchange is a chemical reaction in which free mobile ions of a solid, the ion exchanger, are exchanged for different ions of similar charge in solution. The exchanger must have an open network structure, either organic or inorganic, which carries the ions and which allows ions to pass through it.
Why do we use ion exchange chromatography? Ion exchange chromatography is commonly used to separate charged biological molecules such as proteins, peptides, amino acids, or nucleotides. The amino acids that make up proteins are zwitterionic compounds that contain both positively and negatively charged chemical groups.
What is ion exchanger in ion exchange chromatography? Ion exchangers are solid materials or liquid solutions which are able to take up (or absorb) positively or negatively charged ions from aqueous electrolyte solutions and at the same time release other ions of equivalent amount into the aqueous solution.
