Abstract: In one exemplar embodiment, a chemiluminescent nitrogen detector for detecting chemically-bound nitrogen in an organic compound is provided in which a discrete sample of the organic compound containing the chemically-bound nitrogen is injected into a high temperature furnace where the sample is pyrolyzed at extremely high temperatures in an oxygen rich atmosphere to form nitric oxide. The pyrolysis gases, including nitric oxide is then applied to a drying means for eliminating a substantial quantity of water vapor from the carried pyrolysis gases to insure that the dew point of the gases is below the operating temperature of a nitric oxide and ozone reaction chamber. The nitric oxide and ozone are mixed in a reaction chamber to form metastable nitrogen dioxide which instantaneously relaxes to its ground state with a resulting photo-emission of light energy.
