  "id": "MLC-T-CHM-013041",
  "term": "Direct insertion probe",
  "field": "Chemistry",
  "definition": "A device used in mass spectrometry to introduce solid or liquid samples directly into the ion source region of the mass spectrometer. The sample is typically placed in a small crucible or on a filament at the end of a rod, which is then inserted through a vacuum lock. Heating the probe volatilizes the sample for ionization and analysis.",
