Detection of explosives on human nail using confocal Raman microscopy
Trace amounts of explosives were detected on human nail using confocal Raman microscopy. Contamination of the nail can result from the manual handling, packaging or transportation of explosive substances. Raman spectra were obtained from pentaerythritol tetranitrate (PETN), trinitrotoluene (TNT), ammonium nitrate and hexamethylenetetramine (HMTA) particles on the surface of the nail with dimensions in the range 5–10 µm. An added ... إقراء المزيد

In-situ detection of single particles of explosive on clothing with confocal Raman microscopy.

In-situ detection of single particles of explosive on clothing with confocal Raman microscopy.
Confocal Raman microscopy is shown to detect picogram quantities of explosives in-situ on undyed natural and synthetic fibres, and coloured textile specimens leaving potentially evidential materials unaltered. Raman spectra were obtained from pentaerythritol tetranitrate (PETN), trinitrotoluene (TNT), and ammonium nitrate particles trapped between the fibres of the specimens. Despite the presence of spectral bands arising from the natural and synthetic ... إقراء المزيد

Raman spectroscopy and security applications: the detection of explosives and precursors on clothing

Raman spectroscopy and security applications: the detection of explosives and precursors on clothing
This study describes the application of confocal Raman microscopy to the detection and identification of explosives and their precursors _in situ_ on undyed natural and synthetic fibres and coloured textile specimens. Raman spectra were obtained from explosives particles trapped between the fibres of the specimens. The explosives pentaerythritol tetranitrate (PETN), trinitrotoluene (TNT), and ammonium nitrate as well as the explosives ... إقراء المزيد

Forensic and security applications of a longwavelength dispersive Raman system

Forensic and security applications of a longwavelength dispersive Raman system
A novel dispersive system operating at 1064-nmexcitation and coupled with transfer electron InGaAs photocathode and electron bombardment CCD technology has been evaluated for the analysis of drugs of abuse and explosives. By employing near-IR excitation at 1064-nm excitation wavelength has resulted in a significant damping of the fluorescence emission compared to 785-nm wavelength excitation. Spectra of street samples of drugs ... إقراء المزيد
