  "term": "Zone",
  "field": "Chemistry",
  "definition": "A region within a chromatographic column or separation system where a particular component or group of components of a mixture is concentrated. As the mobile phase carries the sample through the stationary phase, different components migrate at different rates, forming distinct zones. The efficiency of a chromatographic separation is often evaluated by the sharpness and separation of these zones.",
