i-SCAN

IMS Handheld Trace and Vapours Detector for Explosives and Narcotics

i-SCAN is a handheld sensor that Employs Ion Mobility Spectrometry to detect explosives, drugs and toxic substances,
in the air around controlled objects, on the surface of different objects or on fingers and clothes.

Applications

  • Vehicle, cargo, luggage and people inspection at customs control, airport security, border control and military checkpoint
  • Suspects inspection by law- enforcement officials
  • Expert criminology laboratories of different departments
  • Analytical laboratories of industrial enterprises
  • Scientific research organizations

Advantages

  • Hand Held
  • Small, light weight
  • Non Radioactive Ioniozation source
  • Ultra High Sensitivity - Detects trace particles and vapour; Low false negative results
  • Battery Operated
  • Scan time – 5 seconds
  • Automated Process
  • No high-priced expendable materials required
  • Expandable threat library - Open database of substances with customer updating and expansion possibility
  • Wide range of detected chemical agents including home-made peroxide explosives

Methodology

  • Employs Ion Mobility Spectrometry (IMS)
  • ISCAN Detector operating software analyzes the peaks of received range of inspected substances, using mathematical expectation (assembly average) and time dispersion, corresponding to peaks with target substances taken from the systems’ library.
  • Combined sampling apparatus allowing both sampling of air containing vapors and suspended particulate matter and sampling of particles collected on a special sampling wipe.
