One of the water molecules is replaced by a sulphate ion. Notice the change in the charge on the ion. Two of the positive charges are cancelled by the presence of the two negative charges on the sulphate ion.
WebThere are two types of ion exchange SPE, cation exchange and anion exchange. For this example, we would select cation exchange because the analyte we wish to retain is cationic (positively charged). This separation will be a basic 3-step approach to SPE (Figure 2A), starting with the first step of loading the sample onto the cartridge. WebIon Exchange Chromatography Workflow. After loading an impure protein sample onto an ion exchange chromatography column, the column is washed to remove undesired proteins and other impurities, and then the protein (s) of interest is eluted using either a salt gradient or a change in pH. Fig. 3. Salt gradient elution.
