Trace Explosives Detection

Robust, Field-Deployable Trace Explosives Detection

Background

Trace Explosives Detection

From airport security and cargo inspection to protecting public spaces such as arenas, the demand for fast, accurate detection and classification of explosives residue is growing.  It requires tools to quickly and safely identify explosives and residues.

Coupled to innovative sampling and ion source systems capable of efficiently sampling the residue and introducing the gas- and/or aerosol-phase material, TOFWERK offers robust, field-deployable mass spectrometers for increased specificity and accuracy for the measurement of explosive residues.

Solutions

  • Real-Time Trace Level Explosives Detection Using the Vocus PTR-TOF

    • Highest sensitivity available with sub-ppt Limits of Detection
    • High mass resolving power enables identification of individual compounds within complex mixtures
    • Real-time and fast time response with no sample preparation
    • Full spectrum acquisition allows simultaneous measurements of wide range of chemical properties and vapor pressures
    • NH4+ reagent ions optimization for trace explosives detection

    What is PTR-MS?

    Detection of TATP

    Fast, real-time detection of Triacetone Triperoxide (TATP). A human subject carrying a small amount of TATP walked several times in front of the Vocus CI-TOF detector. Ventilation directed the low-concentration plumes of TATP to the detector inlet. Each detection of the TATP “threat” is visible as a sharp spike.
