Time-of-Flight (ToF) Mass Analyzers

The basic principles of mass analysis using time-of-flight mass analyzers are relatively straightforward in comparison to many of the other typical mass analyzing devices. Ions are extracted (or produced) in short bursts or packets within the ion source and subjected to an accelerating voltage. The ions then drift or fly down an evacuated tube of set length.

Topics include:

Time-of-flight (ToF) mass analyzers
Equations of motion
Time-of-flight (ToF) resolution
The reflectron
Increased resolution using reflectrons
Time-of-flight performance limitations
Orthogonally accelerated ToF (oaToF) instruments
oaToF pusher electrodes
oaToF pusher pulse rate
oaToF deflecting voltage
