  "id": "MLC-T-CHM-005879",
  "term": "In-needle capillary adsorption trap",
  "field": "Chemistry",
  "definition": "A sample preparation device in which a capillary coated on its inner wall with a sorbent is placed inside a needle, so that sample is drawn through it in an in-tube extraction format. Analytes adsorb onto the coating, are then desorbed, for example thermally in a gas chromatograph injector, and are transferred to the instrument for separation and detection.",
