Cards (5)

    1. Vaporisation
    2. ionisation
    3. acceleration
    4. ion drift
    5. detection
  • Vaporisation
    sample is vaporised
  • Ionisation
    sample is bombarded with high energy electrons which ionises the atom to form +1 charge
  • Acceleration
    positive ions passed through electric field
    particles with lower m/z ratio will accel quicker
  • detection
    ions are detected as electrical current is made when particle hits the plate
