Time-of-flight mass spectrometer An instrument making use of the fact that ions of different mass/charge ratio, and all with the same initial translational energy, require different times to traverse a given distance in a field-free region. |

| Time-of-flight mass spectrometer |
|---|
|
An analytical instrument in which ions are formed and accelerated and their flight times measured to determine their mass. Time-of-flight mass spectrometers can be distinguished by those that accelerate ions to constant momentum (in which case flight times are linear with mass) and constant energy (in which case flight times are proportional to the square root of mass). Time-of-flight mass spectrometers were originally known as velocitrons. |
