MS - Time of flight Mass spectrometer (TOFMS)

The time-of-flight mass spectrometer (TOF) takes advantage of the fact that the ions all have the same energy when they enter the analyzer and that light ions are therefore faster than heavy ones. The resolution is up to R = 15,000 (10% method). Therefore, light ions reach the detector sooner than heavy ions. In practice, devices with ion mirrors have proven successful, where the flight distance is doubled by an additional electric field at the end of the original flight direction. In addition, this technique achieves further focusing, which minimizes the variance in the speed of the ions due to the Doppler effect.
