Abstract
An explosive detection system in which vapor leaking from luggage is sampled by a sampling probe, negative corona discharge is used to ionize the vapor, and a mass spectrometer is used to detect the ionized vapor, thereby judging whether an explosive is present or not.
Claims2
An explosive detection system, comprising a sampling probe for sampling vapor, means for subjecting the sampled vapor to negative corona discharge to ionize the vapor, and a mass spectrometer to detect the ionized vapor, thereby judging whether an explosive is present or not;
- wherein the explosive detection system forms a part of a carriage vehicle, and wherein the explosive detection system further comprises a temperature adjuster and a pressure adjuster.
A carriage vehicle with an explosive detection system, the explosive detection system comprising:
- a temperature adjuster;
- a pressure adjuster;
- a sampling probe for sampling vapor;
- an ion source utilizing negative corona discharge for ionizing chemicals in the sampled vapor;
- and
- a mass spectrometer to detect the ionized chemicals as an indication of the presence or absence of an explosive.
