    Abstract: A method and device for detecting explosive compounds in an air sample in which the air sample is filtered with activated carbon treated with a weakly basic solution, after which the air sample is divided into two parts, with one part being heated at lower temperatures to decompose non-explosive nitrogenous compounds and the second part being heated at higher temperatures to decompose explosive nitrogenous compounds. Nitrogen dioxide is measured in both portions of the air sample with a spectrographic detector, and the presence or absence of explosive nitrogenous compounds in the air sample is determined.

    Abstract: The nitrogen oxide analyzer obtains the ozone concentration-luminescence response characteristics that show the relationship between the ozone concentration and the light intensity by chemiluminescent response obtained by varying the ozone concentration alone in a steady state, and sets the relationship of the parameter that determines an average period of the sample gas passing the reactor so that the luminescence response is generated in the reactor alone even though the ozone concentration of the ozone-containing gas changes within a predetermined range based on the ozone concentration-luminescence response characteristics.

    Abstract: Localized catalyst activity in an SCR unit for controlling emissions from a boiler, power plant, or any facility that generates NOx-containing flue gases is monitored by one or more modules that operate on-line without disrupting the normal operation of the facility. Each module is positioned over a designated lateral area of one of the catalyst beds in the SCR unit, and supplies ammonia, urea, or other suitable reductant to the catalyst in the designated area at a rate that produces an excess of the reductant over NOx on a molar basis through the designated area. Sampling probes upstream and downstream of the designated area draw samples of the gas stream for NOx analysis, and the catalyst activity is determined from the difference in NOx levels between the two probes.
