    Low-limit photo-acoustic detection of solid RDX and TNT explosives with carbon dioxide laser
    ( 2006-03-01) Chaudhary, A. K. ; Bhar, G. C. ; Das, S.
    We report the absorption spectra of RDX and TNT explosive samples in solid form at room temperature using a carbon dioxide laser-based photo-acoustic technique. A continuous wave 12C16O2 laser, tunable between the 9.25-10.74 μm wavelength region, was used as an energy source. Interference-free limits of detection of solid RDX and TNT in simulated samples are estimated to be 10.0 and 16.5 ppbw, respectively. ©2006 Springer Science+Business Media, Inc.
