Abstract
An explosive detection system including a sample injection region, an ion source region for generating ions of a sample injected by the ion injection region, a mass analysis region for analyzing mass of the ions, a heater for heating the sample injection region and the ion source region, a plurality of pumps for exhausting a chamber in which the mass analysis region is disposed, and a controller for controlling the regions and the plurality of pumps. The controller conducts control so as to heat the sample injection region and the ion source region with the heaters, then reduce heating electric power supplied to the heaters in order to prevent a predetermined electric power value from being exceeded, and drive the plurality of pumps successively to exhaust the chamber.
