How Cation Exchange Chromatography Works
This animation visualizes a charged resin column where negatively charged beads bind positively charged molecules flowing through in a mixed sample. It shows how molecules with stronger positive charge stick more tightly, while weakly charged or neutral molecules pass through first. An increasing salt gradient is shown displacing bound cations in order of charge strength, achieving separation. Useful for students studying biochemistry, analytical chemistry, or protein purification techniques.
