Atomic Abundance Flashcards

Q

5 steps of Mass Spectrometer

A
  1. vaporization (heat to gas)
  2. ionization (bombard w high energy electrons, get to single positive charge)
  3. acceleration (pass through slits to increase speed)
  4. deflection (passed over magnetic field, deflections proportional to charge/mass ratio, smaller masses deflect/turn more than heavy ones)
  5. detection (signals to recorder, look at graph)
