non dispersive infrared analyser used for diesel engines

Nondispersive Infrared Analysers Big Chemical Encyclopedia

Nondispersive Infrared Analysers Hannaker and Buchanan [82] differ from Menzel and Vaccaro [46] in that they use Carbosorb or soda asbestos tubes to estimate the carbon dioxide produced, instead of the nondispersive infrared analyser used by the latter workers. Van Hall et al. [100] inject a 20 litre sample into a hightemperature furnace at 950 °C containing catalyst to promote oxidation ...

Nondispersive infrared sensor Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector. It is nondispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing. The majority of NDIR sensors use a broadband …

Infrared Measurement Principle (NDIR) ecom

A nondispersive infrared sensor is used in gas analysis to determine the gas concentration. NDIR analysers are particularly suitable for the determination of the concentration of carbon monoxide, carbon dioxide or hydrocarbons in a gas. Components of this process are a source of infrared radiation, an irradiated tube (cuvette) with the gas to be analysed, a wavelength filter and an infrared detector. The gas which has to be analysed …

NonDispersive Analyzers Inst Tools

Industrial nondispersive analyzers typically use either infrared or ultraviolet light sources, because most substances of interest absorb wavelengths in those regions rather than in the visible light spectrum. Nondispersive spectroscopy using infrared light is usually abbreviated NDIR, while nondispersive spectroscopy using ultraviolet light is abbreviated NDUV and nondispersive spectroscopy using …
