  "id": "MLC-T-CHM-006100",
  "term": "Ion-exchange chromatography",
  "field": "Chemistry",
  "definition": "A chromatographic separation technique that separates ions and polar molecules based on their reversible electrostatic interactions with a stationary phase bearing charged functional groups. The separation occurs as analytes compete with counter-ions in the mobile phase for binding sites on the resin. This method is widely used for the separation of proteins, amino acids, and inorganic ions.",
