Ion exchange chromatography

Ion exchange chromatography is a technique used to separate charged molecules, like proteins or amino acids, based on their electrical charges. It involves a resin or bead that has charged groups attached to it. When a mixture passes through, molecules with opposite charges stick to the resin, while others flow through. By changing the salt or pH in the solution, the bound molecules are released at different times, allowing their separation. This method is widely used in labs to purify and analyze various biological substances efficiently.
