1) Vapourisation
Changing a solid or liquid to a gaseous state if need be.
1 of 5
2) Ionisation
The atom is ionised by removing electrons to give a positive ion - for all atoms. This is because mass spectrometers only work with positive ions.
2 of 5
3) Acceleration
Ions are accelerated to give the same kinetic energy.
3 of 5
4) Deflection
Ions are then deflected by a magnetic field according to mass. E.g. Lighter equals greater deflection.
4 of 5
5) Detection
Ions are then detected electrically by a machine.
