There are several types of devices and methods that can be used to identify explosives
. Below are four examples of detection devices:
Particulate Explosives Detector
This is a device approximately 15 x 12 x 5 inches, which requires either AC or battery power
. It can detect the following explosives:
This device uses IMS (ion mobility spectroscopy) to detect micron-size particles used in explosives. A sample size of one nanogram is sufficient to be detected.
To use it, swipe the suspected material with a sample cloth or cotton glove. Analysis time is approximately 3 seconds. A visual display will light up with a numerical scale of the materials detected. An audible alarm will sound based on a user-defined threashold.
Portable X-Ray System
This device uses a Polaroid
radiographic film to create detailed radiographs of items scanned. It required AC input
, or a rechargable battery
. To use it, point the lens at the suspected parcel and view the image on the film or screen.
Spray Bomb Detector
A portable spray can
used in conjunction with laminated test paper
. This method allows detection of both plastic and traditional TNT traces on parcels, hands and fingerprints. The test kit
contains the test paper and two cans of spray labelled E and X. To use it, first rub the paper over the suspected item and then spray the paper with the canister
labelled E. If the paper turns violet
, then there are traces of TNT evident. If there is no reaction, spray the paper with the canister labelled X. If the paper then turns pink
, there are traces of plastic explosives.
Bomb Range Detector
This is a car-mounted
detector of radio-controlled explosives
. The unit automatically scans and transmits on every radio frequency
in a one-kilometer radius. When a radio-controlled explosive is in the area, the device jams it to render it harmless
until it can be found and defused.
