And so following the addition of our peptide into this solution, at this temperature, for 24 hours, we're going to have a solution that consists of these individual constituent amino acids floating around in that water. Now, what exactly is the next step? So once we separated these amino acids, now we want to actually separate them into these individual compartments. So how exactly do we separate them into individual beakers? So we're going to basically use a procedure that we spoke about earlier. We're going to use the ion exchange chromatography technique.
