Time-of-flight mass spectrometer with spatial focusing of a broad mass range


The invention relates to time-of-flight mass spectrometers which operate with pulsed ionization of superficially adsorbed analyte substances and with an improvement in the mass resolution by means of a time-delayed start of the ion acceleration; in particular with ion-accelerating voltages which change over time after a delayed start in order to obtain a constant mass resolution over broad mass ranges.
