  "term": "Image current detection",
  "field": "Chemistry",
  "definition": "A method of detecting ions in a mass spectrometer, particularly in Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometry, by measuring the oscillating electrical current induced by the coherent motion of ions. As ions orbit in a magnetic field, their collective motion induces an image current in detection plates. This current is then Fourier transformed to yield a mass spectrum.",
