Field Portable Biosensors for the Detection of Explosives in Groundwater
EXTENDED ABSTRACT Biosensors provide a sensitive, specific, rapid, portable, and inexpensive means to fulfill the need for rapid on-site determinations of hazardous pollutants (e.g., explosives). Recent advances in instrumentation at NRL have led to two methods for measuring TNT and RDX: the FAST 2000 and the Analyte 2000. Engineering and design of both instruments was performed by Research Int...
متن کاملDeep ultraviolet resonance Raman excitation enables explosives detection.
We measured the 229 nm absolute ultraviolet (UV) Raman cross-sections of the explosives trinitrotoluene (TNT), pentaerythritol tetranitrate (PETN), cyclotrimethylene-trinitramine (RDX), the chemically related nitroamine explosive HMX, and ammonium nitrate in solution. The 229 nm Raman cross-sections are 1000-fold greater than those excited in the near-infrared and visible spectral regions. Deep...
متن کاملUV gated Raman spectroscopy for standoff detection of explosives
Real-time detection and identification of explosives at a standoff distance is a major issue in efforts to develop defense against so-called improvised explosive devices (IED). It is recognized that the only method, which is potentially capable to standoff detection of minimal amounts of explosives is laser-based spectroscopy. LDS technique belongs to trace detection, namely to its micro-partic...
متن کاملDetection of illicit chemicals by portable Raman spectrometer
The Raman spectrometers can be built as the portable devices and can be used in various places to detect illicit chemicals. This method has become popular due to deficiency of other fast methods that could be applied against terrorist attacks or could help police at their work. The Conception of a portable Raman spectrometer has been presented. The Description enclosures the presentation of the...
متن کاملAdapting Raman spectra from laboratory spectrometers to portable detection libraries.
Raman spectral data collected with high-resolution laboratory spectrometers are processed into a format suitable for importing as a user library on a 1064 nm DeltaNu first generation, field-deployable spectrometer prototype. The two laboratory systems used are a 1064 nm Bruker Fourier transform (FT)-Raman spectrometer and a 785 nm Kaiser dispersive spectrometer. The steps taken to adapt for dev...
