Raman versus Trace Raman Spectroscopy Identification IMS Trace Detection q • • q Used to identify bulk liquids and solid materials that are visible to the human eye Raman spectroscopy has extremely high accuracy and very low false alarm rate (< 1%) Capable of identifying thousands of chemicals and mixtures Can identify raw materials used in manufacture of HMEs, not just finished explosives First. Defender is field instrument, rugged and decon-able Ready to go – no warm up time required No consumables FD can be upgraded in the field with new library items as new threats emerge • • © Ahura Scientific, Inc. 2007 Used to identify the presence of trace explosives that cannot be seen High nuisance alarm rate (~10%) and cannot be used on bulk quantities (will saturate the detector) Only identifies finished explosives Can identify 5 – 10 single chemicals Not typically decon-able Dopant and dessicant consumables typically required ~2 - 24 hour warm up time Slide 5 5 © Ahura Scientific 2008

First. Defender Explosives Identification q Hand Held Chemical Identification System • > 6500 Substance Library • Explosives & Precursors • CWA and Industrial Chemicals q Simple User Interface • Designed for Tactical Field User • Point & Shoot, Vial or Flex Probe Mode • Samples Through Containers q Quick – Accurate Response • Unknown substance is scanned with 785 nm laser – scattered light is measured and compared to library of chemical spectrum • Capable of identifying mixtures q Light Weight – Ergonomic Design • < 4 pounds • Rugged exterior can be submerged and decon’d © Ahura Scientific, Inc. 2007 Slide 13 13 © Ahura Scientific 2008
Principles of Operation q Detection Method – Raman Spectroscopy • No Sample Handling or Preparation • Designed for tactical, point and shoot applications • Unaffected by Strong IR Absorbers (Water, CO 2, Glass) • Excitation Wavelength Can Penetrate Container Materials § Beer bottles, wine bottles, water bottles, zip-lock bags, etc. • Unique spectrally rich signature for identification q Limitations • Does not penetrate opaque containers • Dark colored solid materials, black powder • Fluorescence can limit household product identification • Fluorescence can increase measurement time © Ahura Scientific, Inc. 2007 Slide 14 14 © Ahura Scientific 2008
Use Modes Vial Ideal when environment does not allow for point and shoot, and for when sampling is done for evidence collection Use caution on dark colored substances Point-and-Shoot Flex Probe Ideal when you do not want to open container Ideal for hard to reach locations, and for freeing hands and fixing probe on sample Best Tactical Sampling Option © Ahura Scientific, Inc. 2007 Sample Time will be longer than point and shoot Slide 15 15 © Ahura Scientific 2008
