6. After being Ionised in the Mass Spectrometer what charge is left on the majority of atom/molecule?

  • 1+
  • 2+
  • 1-
  • 2-

7. About 5% of the atoms/molecules form 2+ charge?

  • True
  • False

8. How are the positve ions accelerated in the Mass Spectrometer?

  • Attracted towards a negatively charged plate
  • Pushed by other ions

9. What do the ions speed depend upon?

  • Their Mass
  • The element it is

10. What deflects the ions?

  • Magnetic Field
  • Current

11. Heavier ions are defelcted less and lighter ions are deflected most?

  • True
  • False

12. How is an ion detected?

  • Hit the detector, accept an electron, lose their charge and create a current
  • Hit the detector, reject an electron, keep the same charge and create a current
  • The computer just detects it

13. what is on the x axis of a mass spectrum graph?
