Mass Spec

HideShow resource information
Electrospray ionisation
High voltage applied to the tip of a capillary to produce charged droplets which evaporate to produce gaseous charged ions.
1 of 5
Acceleration
Electric field applied to give all ions a constant kinetic energy
2 of 5
Ion drift
Ions enter a flight tube with no electric field. Smaller ions travel faster and heavier ions move more slowly
3 of 5
Ion detection
Ions arrive at the detector and produce a small electric current due to their charge and then the detector records the different flight times of the ions
4 of 5
Data analysis
Flight times are analysed and a mass spectrum is produced by data analyser
