摘要： A gas analyzer system for providing a spectroscopic analysis of the sample gas. This analysis is accomplished by first introducing the sample gas into the inlet of the system and transporting it to a spectral analyzer. The sample gas is then spectrally analyzed and the analyzer outputs a signal indicative of a radiation intensity spectrum associated with the analyzed sample gas. A processing unit uses the analyzer signal to detect the presence of one or more prescribed gases and to determine the concentration of each of the prescribed gases in the sample gas. Next, the reacting agent is supplied to the sample gas to convert one or more gases whose presence in the sample gas cannot be detected via spectral analysis due to the masking effects other gases present in the sample gas. The masked gases are converted to secondary gases at least one of which is readily detectable via spectral analysis. This converting process occurs in the time it takes for the sample gas to transit uninterrupted through the system to the analyzer. The modified sample gas is spectrally analyzed, and the processing unit detects the presence of the masked gases and determines the concentration of each. The system may be employed to monitor certain environmental gases contained within industrial emission. In such a case, the prescribed gases are nitrogen dioxide and sulfur dioxide, and the masked gases are nitric oxide, ammonia, and hydrogen sulfide.

摘要： A system for continuously monitoring the hydrogen sulfide concentration present in the atmosphere above a waste water stream, such as a sewerage stream, and for controlling the amount and time of injecting a specified chemical into the waste water stream in order to control the quantity of hydrogen sulfide which would evaporate into the atmosphere. This system comprises the steps of obtaining a sample of atmosphere above the stream; routing the sample of air through a sensor for determining the concentration of hydrogen sulfide gas within the quantity of air determining the amount of an amine-based dopant to add to the waste water; sending a signal from the controller to a chemical injection pump for injecting the determined quantity of chemical compound into the waste water stream to absorb some of the hydrogen sulfide gas; continually monitoring the stream for determining the concentration of hydrogen sulfide gas in the stream following the introduction of chemical compound thereunto; and adding additional compound on a continuing basis, as needed, depending on the concentration of hydrogen sulfide within the stream.

摘要： The present invention relates to a biomimetic sensor for detecting the presence of airborne toxins, such as carbon monoxide, mercury, ethylene oxide, volatile organic materials, and hydrogen sulfide. The biomimetic sensor, which has a functional life of at least one year, comprises a porous, semi-transparent substrate into which is impregnated a self-regenerating chemical sensor reagent. The response of the biomimetic sensor mimics the human response to such toxins, with respect to sensitivity and affinity. The extended functional lifetime of the biomimetic sensor and the mimicking of the human response to the toxins are achieved by the use of a molecular encapsulant that encapsulates at least one component of the chemical sensor reagent.

摘要： A selected component of a fluid mixture, for example a reduced sulfur compound vapor in air, is detected by selectively adsorbing the component onto a conductive thin layer of material having a chemical affinity for such component and observing the resultant change of electrical resistivity of the layer. The sensitivity of the detector changes with accumulation of the component on the sensor. The accumulation of the component on the sensor is removed by oxidizing and evolving the component from the sensor to restore the sensor to a linear operating region. The accumulated component is preferably oxidized by reacting the component with ozone. The dynamic range of the sensor is increased by counteracting the tendency for the component to accumulate by continuously feeding back ozone to or controlling the temperature of the sensor so that the sensor operates in a linear region near null.
