Vaporisation
|
When the sample is turned into gas(vaporised)
|
|
|
Ionisation
|
Gas particles bombarded with electrons to ionise them. Electrons are knocked of the particles, leaving positive ions.
|
|
|
Acceleration
|
Positive ions are accelerated by an electric field.
|
|
|
Deflection
|
Positive ions are altered with a magnetic field. Lighter ions have less momentum than heavier ions.
|
|
|
Detection
|
As the magnetic field strength slowly increases different ions (with a higher mass/charge ratio) reach the detector. As ions hit the detector they cause a current to flow.
