Ion Exchange Chromatography Discussion: The first exercise preformed in this lab was ion exchange chromatography. The purpose of this experiment is to separate molecules based on their differences in charge. Since it is based on charge the amino acids in the cation exchange column‚ if negatively charged‚ flow through the column first because they don’t want to bind to the sodium ions. The positively charged ions will elute last at the highest ph because they bind to the negatively charged beads
