Optical spectral analysis agents

Early warning capability of chemical or biological threats is cracial for the safety and security of the public as well as militaiy forces, and it has been a driving force for development of stand-off detection technologies. The current stand-off monitoring systems for chemical or biological agents are mostly based on optical spectral analysis and deployed on mobile/fly-by platforms (1-3). These systems offer excellent chemical identification capability, but are in... 

Optical remote sensing (ORS) technologies, employing infrared spectral analysis techniques, have been utilized in the development of chemical agent standoff detection technologies. Within the ORS technologies, there are two types of remote sensing systems passive and active (laser). The section below only looks at the passive system, which employs a Fourier Transform Infrared (FTIR) spectrometer. 

Determination of trace impurities in uranium is one of the potentially major applications of ICP-MS because the mass spectrum of uranium from an ICP is very simple. Spectral overlap with analyte signals is not a problem, as is often the case in many optical emission methods. In ICP-MS, however, this analysis is often limited by suppression of analyte signal induced by the large excess of uranium in the solution. Various selective extracting agents (e.g, tri-n-octylphosphine oxide) have been...
