  "id": "MLC-T-CHM-012698",
  "term": "Wien filter",
  "field": "Chemistry",
  "definition": "A device that selects charged particles based on their velocity by applying perpendicular electric and magnetic fields. Only particles with a specific velocity, where the electric and magnetic forces cancel each other, pass through undeflected. This filter is commonly used in mass spectrometry as a velocity selector for ion beams.",
