Abstract
A tandem mass spectrometry system has a first mass spectrometer for creating and extracting precursor ions. The ions are introduced into a decelerating electric field at a slight angle to the direction of the electric field which is formed by first through third electrodes. An accelerating electric field perpendicular to the decelerating electric field is applied at the instant when the ions arrive at the midpoint between the second and third electrodes at which the velocities of the ions in the direction of the decelerating field are zero.
