Abstract
A method and apparatus for screening an object for the presence of an explosive, chemical warfare agent, biological warfare agent, drug, metal, weapon, and/or radioactive material. The apparatus includes a portal through which the object is arranged to pass, the portal including a housing equipped with an ion mobility spectrometer and a surface acoustic wave device for detecting explosives, drugs and chemical warfare agents. In another embodiment the housing is equipped with a biological warfare agent detector, chemical warfare agent detector, metal detector, x-ray system, and/or radiation detector.
Claims60
An apparatus for screening an object for the presence of an explosive, comprising:
- a portal through which said object is arranged to pass, said portal having a housing equipped with:
- an ion mobility spectrometer operatively arranged to primarily detect said explosive;
- and,
- a surface acoustic wave device operatively arranged to secondarily detect and confirm said explosive detected by said ion mobility spectrometer.
An apparatus for screening an object for the presence of a chemical warfare agent, comprising:
- a portal through which said object may pass, said portal having a housing equipped with:
- a surface acoustic wave device operatively arranged to primarily detect said chemical warfare agent;
- and,
- an ion mobility spectrometer operatively arranged to secondarily detect and confirm said chemical warfare agent detected by said surface acoustic wave device.
An apparatus for screening an object for a threatening agent, comprising:
- a portal through which said object may pass, said portal having a housing equipped with:
- a surface acoustic wave device operatively arranged to detect said threatening agent;
- an ion mobility spectrometer operatively arranged to detect said threatening agent;
- and,
- a biological warfare agent detector operatively arranged to detect said threatening agent.
An apparatus for screening an object for a threatening agent, comprising:
- a portal through which said object may pass, said portal having a housing equipped with:
- a chemical warfare agent detector operatively arranged to detect said threatening agent;
- a biological warfare agent detector operatively arranged to detect said threatening agent;
- and,
- a metal detector operatively arranged to detect said threatening agent.
A method of screening an object for the presence of an explosive, comprising:
- passing said object through a portal which houses a plurality of detectors;
- sampling air which has passed over said object with an ion mobility spectrometer operatively arranged to primarily detect said explosive;
- and,
- sampling air which has passed over said object with a surface acoustic wave device operatively arranged to secondarily detect and confirm said explosive detected by said ion mobility spectrometer.
A method of screening an object for the presence of a chemical warfare agent, comprising:
- passing said object through a portal which houses a plurality of detectors;
- sampling air which has passed over said object with a surface acoustic wave device operatively arranged to primarily detect said chemical warfare agent;
- and,
- sampling air which has passed over said object with an ion mobility spectrometer operatively arranged to secondarily detect and confirm said chemical warfare agent detected by said surface acoustic wave device.
