Recognizing the need to monitor formaldehyde gas in residential and industrial buildings,_x000D_ Giner, Inc. (Giner) will continue the successful work started in Phase I and will develop,_x000D_ fabricate and demonstrate a formaldehyde gas monitor that is capable of continuously_x000D_ measuring formaldehyde in the range of 0-2000 parts per billion (ppb) with a resolution of 10 ppb. The wireless c ...

Infrared tunable diode laser spectrometers provide a highly effective means of measuring trace concentrations, with either remote sensing or with advective sampling. It is often desirable to measure more than one trace gas at a time. This is especially true when gas emissions are strongly correlated, such as in combustion emissions where measuring both the CO2 concentration and another minor con ...

Chlorinated hydrocarbons represent the most prevalent contaminants of groundwater in the country. When released in the subsurface, they tend to persist below the water table, and it can take decades or centuries before slow-moving groundwater completely dissolves accumulations of chlorinated solvent product. Analytical methods currently available for monitoring these compounds require extensive ...

Heavy metal species mobilized and released into the environment by technological activities tend to persist indefinitely, circulating and eventually accumulating throughout the food chain, posing a serious threat to the environment, animals, and humans. Typical industrial metal-containing discharges can be considered as point-source emissions, which in turn offer the possibility of feasible remed ...

Laser-induced fluorescence (LIF) can sometimes be used as a diagnostic device in biology and medicine. In general, LIF has difficulties in relating the fluorescence spectra to the concentration of the emitters within the tissue, in identifying different species, and in the possibility of destroying the molecules being probed if the wrong excitation wavelength is chosen. Many of the problems asso ...

The problem addressed in this project is the need to monitor oxides of nitrogen(NOx, ie NO and NO2) levels in the combustion gases of stationary sources suchas power plants in order to facilitate on-line control of the scrubbers that willbe used to remove those pollutants. Since the measurements are in the parts permillion range, simpler and less expensive instruments than those currently used,su ...

Billions of gallons of oily wastewaters are generated daily by a variety of industrial sources. A large fraction of these are oil/water emulsions for which current treatment technologies are often costly and ineffective. Although such emulsions can be separated using crossflow filtration technology, conventional crossflow membranes typically are uneconomic for performing such treatment due to st ...

Vapor permeation with highly permeable and organic-selective membranes is becoming an increasingly popular technique for preventing VOC emissions that are generated by a variety of stationary sources, including solvent and surface coating operations, gasoline storage operations, and printing operations. A limitation of current vapor permeation (VP) processes is the upper temperature limit for pol ...

The development of an instrument for continuously monitoring SO2 levels in fluegas is proposed. The SO2 will be detected by means of an electrochemical sensorcell, which operates in a three-electrode potentiostatic mode. The proposedinnovation is develop-ment of an advance sensor cell which uses a high-temperature solid polymer eleobjectives of the proposed program are 1) identification of poten ...
