Abstract
There is disclosed a mass spectrometer capable of performing a mass analysis by accelerating ions to high energies. This spectrometer has a drift zone consisting of a conductive tube located in the ion path between the ion source and the analyzer. A voltage is applied to the drift zone from a voltage source via a switch such that the voltage applied to the drift zone is switched between a low potential V and an accelerating voltage Va of several kilovolts.
