Collision quadrupole

{
  "id": "MLC-T-CHM-002227",
  "term": "Collision quadrupole",
  "field": "Chemistry",
  "definition": "A radiofrequency-only quadrupole mass filter used as a collision cell in tandem mass spectrometry. Ions are guided through this device while undergoing collisions with a buffer gas, leading to fragmentation. The RF field confines the ions radially, preventing their loss during the collision process, and it does not perform mass selection.",
