  "id": "MLC-T-CHM-003152",
  "term": "Dielectric barrier discharge ionization",
  "field": "Chemistry",
  "definition": "An ambient ionization method for mass spectrometry that uses a plasma generated between two electrodes separated by a dielectric material. A high alternating voltage applied across the electrodes creates a non-thermal plasma in the gas, which is often helium or nitrogen, flowing between them. This plasma contains excited species, ions, and radicals that ionize analyte molecules present on a surface or in a gas stream introduced into the discharge region.",
