  "term": "Thin-layer chromatography",
  "field": "Chemistry",
  "definition": "A chromatographic technique where the stationary phase is a thin layer of adsorbent material, such as silica gel or alumina, coated onto a flat, inert substrate like glass or plastic. A liquid mobile phase moves up the layer by capillary action, separating components of a sample based on their differential adsorption and solubility. Separated compounds appear as distinct spots or bands.",
