Handheld Explosives Detector

A handheld explosives detector is a portable analytical instrument used to identify the presence of explosive compounds from trace surface residues, bulk material samples, or ambient vapors at security checkpoints, cargo inspection points, and field search operations. These devices are engineered for single-operator use without requiring laboratory support, delivering confirmed substance identification results within seconds to support immediate threat assessment and operational decision-making in active security environments.

Ion mobility spectrometry is the most widely deployed detection technology in handheld explosives detectors, operating by collecting trace particles or vapors from the sample, thermally desorbing them into an ionization chamber, and separating the resulting ions by drift velocity through a carrier gas under an applied electric field. Each explosive compound produces a characteristic drift time signature that the instrument matches against its onboard reference library to generate a positive identification. Detection sensitivity reaches the nanogram to picogram range for compounds including RDX, PETN, TNT, TATP, HMTD, NG, EGDN, and black powder, covering both military-grade explosives and homemade explosive materials encountered in IED construction.

Sample collection uses disposable swabs wiped across target surfaces including luggage exteriors, vehicle steering wheels, door handles, cargo packaging, and personal items. The swab is inserted into the instrument’s heated inlet for desorption and analysis, with the full cycle from sample insertion to result display completing in 8 to 15 seconds. Vapor sampling inlets on compatible models allow direct air analysis without swab collection for standoff screening scenarios.

In Pakistan, handheld explosives detectors are deployed at international airports, seaports, military checkpoints, court complexes, government buildings, and by EOD and counter-terrorism units conducting search operations in areas with confirmed or suspected IED activity.

Tactical Supply Pakistan supplies handheld explosives detectors for airport security, military, law enforcement, and EOD operations requiring reliable trace explosive identification across Pakistan.
