Abstract
An explosive detection system includes an X-ray inspection apparatus, a mover for moving an object to be inspected to the X-ray inspection apparatus, a sample introduction probe for sampling a gas sample from the object to be inspected, a pipe for introducing the sampled gas into a corona discharge region and for subjecting the sampled gas to negative corona discharge to ionize the sampled gas and to generate negative ions. A mass spectrometer is provided to analyze the mass of the negative ions of the sampled gas and to provide results thereof. Inspection by the X-ray inspection apparatus is performed in relation to sampling of the gas sample, and explosive detection system inspects whether or not an explosive is present in the object to be inspected, from the analysis results of the sampled gas.
