Nozzle-skimmer dissociation

{
  "id": "MLC-T-CHM-008088",
  "term": "Nozzle-skimmer dissociation",
  "field": "Chemistry",
  "definition": "The fragmentation of ions that occurs in the region between the atmospheric pressure ionization source nozzle and the skimmer in a mass spectrometer. This dissociation is induced by collisions with residual gas molecules as ions expand into the vacuum, often facilitated by a potential difference between the nozzle and skimmer. It is a form of in-source collision-induced dissociation.",
