91Nitrogen oxide sensor — A nitrogen oxide sensor or NOx sensor is typically a high temperature device built to detect nitrogen oxides in combustion environments such as an automobile or truck tailpipe or a smokestack. Contents 1 Availability 2 Motivating factors 3… …
92Nitrogen Phosphorus Detector — The nitrogen phosphorus detector (NPD) is a form of gas chromatography in which thermal energy is used to ionize an analyte. With this method, nitrogen and phosphorus can be selectively detected with a sensitivity that is 104 times greater than… …
93nitrogen tribromide — noun the binary compound of nitrogen and bromine, NBr; a dark red explosive liquid Syn: tribromamine See Also: nitrogen trifluoride, nitrogen trichloride, nitrogen triiodide …
94nitrogen-fixing — adjective Describing something, normally a plant or microbe, able to convert inorganic nitrogen into a form usable in the biosphere. Legumes are nitrogen fixing plants, growing them actually adds nitrogen to the soil rather than using it up. See… …
95nitrogen cycle — noun The natural circulation of nitrogen, in which atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain where it is assimilated by plants and either eaten by animals (and returned as faeces) or… …
