"OPTRA proposes a Fourier transform phase shift cavity ring down spectroscopy (FT-PS-CRDS) system for high sensitivity detection of air toxic compounds. Our system operates in the 400-4000 cm-1 spectral range wherein lie vapor phase resonance bands for most air toxic compounds and hazardous chemicals; the spectral resolution is 4-16 cm-1, depending on the discrimination requirements. Our approac ...

"This SBIR Phase I project will develop an affordable, sensitive, fast-response solution to real-time monitoring of Elemental Carbon (EC). EcoChem will employ a proven sensor technology, the photoemission aerosol sensor (PAS) to detect EC. The PAS photoionizes carbonaceous aerosols with a unique excimer lamp [Burtscher, 1992] whose wavelength is chosen to selectively ionize EX and polycyclic aro ...

Ammonia has an important role in the chemistry of the atmospheric environment and air quality. Ammonia emissions are a major environmental concern, yet they remain poorly quantified. There is a need for a sensitive ammonia instrument to monitor emissions and evaluate their effects on the local and regional environments. An instrument capable of continuous monitoring is required to understand diurn ...

Clean drinking water is a critical component of the United States infrastructure and is therefore a potential target for terrorists. In addition to physical attacks to the water network including dams, pumping stations and pipelines, there must be vigilance to prevent the water itself from being fouled through the addition of toxic/hazardous chemicals. It is virtually impossible to protect every r ...

Eltron Research & Development, Inc. (Eltron) proposes to develop an ion-selective, polymer membrane electrode capable of detecting perchlorate in water at low parts per billion (ppb) concentrations. With the discovery of perchlorate contamination in an increasing number of drinking water sources and an increase in regulation of perchlorate in drinking water, some wells are shut down because no cos ...

Nitrogen oxides (NOx) contribute to the formation of ground level ozone, aerosols, and acid rain. Considerable progress has been made in reducing emissions from stationary and highway sources. New emissions standards will require that new off-road (non-road) diesel engines achieve emissions of NOx and other species comparable to those from on-road sources. Currently, there are no inexpensive, effe ...

The threat of chemical or biological (CB) attack is real, and there is a recognized need for improved technologies to better respond to these situations. During a CB emergency, first responder units are critical for handling the emergency, and then restoring the environment where it occurred. After a threat has been contained, the first responders, donned in protective gear, must decontaminate the ...

Electrostatic precipitators are widely used for the removal of particulate matter from boiler exhaust gases. The U.S. Environmental Protection Agency (EPA) promulgation of National Emissions Standards for Hazardous Air Pollutants (NESHAP) from Industrial, Commercial, and Institutional Boilers and Process Heaters will require industry to install many new high-performance precipitators on such sourc ...

Biodesel is a fuel that is made from processing vegetable oil or animal fats into a liquid fuel that can be combusted in a standard diesel engine. Biodiesel is made from a renewable resource such as soybeans or tallow, does not contribute to global warming, and can be made from domestic resources. However, the growth of the biodiesel industry has been slowed because the current production processe ...
