Explosive detection system

An explosive detection system comprising:

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

An explosive detection system comprising:

• an absorption region for absorbing vapor from a detection subject substance;
• an ion source region for generating ions of the detection subject substance;
• an absorption pipe laying for coupling said ion source region to said absorption region;
• a mass analysis region for analyzing mass of the ions;
• a first heater for heating said absorption region;
• a second heater for heating said absorption pipe laying;
• a third heater for heating said ion source region;
• a plurality of pumps for exhausting a chamber in which said mass analysis region is disposed;
• and
• a controller for controlling the regions and said plurality of pumps,
• wherein said controller conducts control so as to heat said absorption region with said first heater, said absorption pipe laying with said second heater, and said ion source region with said third heater, then reduce heating electric power supplied to said first, second and third heaters in order to prevent a predetermined electric power value from being exceeded, and drive said plurality of pumps successively to exhaust said chamber.
