How would you use ion exchange chromatography to seperate a mixture of alanine, glutamic acid, and lysine if you wished to maintain the pH at 7.5 and use only a single ion exchange column ( either an anionic or cationic exchanger). Describe the expected order of elution under the conditions which you propose.

Chemistry could follow it to separate and purify your mixture. Be
sure to include details as to how much solvent is used,
concentration of acids and bases, temperatures of any
processes.
