Abstract
An orthogonal acceleration time-of-flight mass spectrometer has: an ion source for ionizing a sample; a conductive box into which the ions are introduced; ion acceleration device causing the ions to be accelerated in a pulsed manner in synchronism with a signal giving a starting point of measurement; and ion detector for detecting the ions in synchronism with the acceleration of the ions. The conductive box is provided with an ion injection port and an ion exit port. A lift voltage is applied to the conductive box. This voltage is switched in synchronism with the signal giving the starting point of the measurement.
