Mass Spec

Cards (6)

  • spec allows us to infer the relative mass of a molecule
  • The 4 stages are:
    • ionisation
    • acceleration
    • ion drift
    • detection
  • Ionisation is where electrons are removed from atoms or molecules, creating positive ions.
  • Acceleration is when the ions are accelerated by an electric field towards the detector.
  • Drift is where the ions travel through a vacuum tube at high speed.
  • molecular ion peak = mass of compound
