These analysers accelerate ions using an electrostatic field of known strength. Smaller and more highly charged ions accelerate faster. m/z is determined by the time taken to reach the detector

Ions pass through an oscillating electrostatic field generated by charged rods - the path of the ions is altered by the field depending on the m/z ratio. By altering the field strength, the spectrometer can detect different m/z ratios

This type of mass spec can be used to determine the mass of an ion up to 4 decimal places. This means the ion can be linked to a single molecular formula (not useful for isomers)

This type of mass spec involves fragmenting the fragments to identify any peaks that may come from impurities.
