  "id": "MLC-T-CHM-012635",
  "term": "Wall-coated open-tubular column",
  "field": "Chemistry",
  "definition": "A type of capillary column used in gas chromatography, characterized by a thin layer of stationary phase coated directly onto the inner wall of the narrow-bore tubing. This design offers high separation efficiency due to the large surface area to volume ratio and reduced resistance to mass transfer. These columns typically have internal diameters ranging from 0.1 to 0.5 mm.",
