A numerical model for calculating carrier gas effects in non‐dispersive infrared gas analyzers was presented in the preceding paper. This model is applied here to sets of data from several analyzers used in measuring atmospheric CO 2 concentrations at a world‐wide network of baseline stations. The agreement between the model and the experimental results is generally satisfactory, and the. What the curriculum thinks you need to know.

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element (e.g 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.

Non-dispersive type infrared absorption sensors are widely used for various types of gas measurements such as carbon monoxide (CO), carbon dioxide (CO 2), and hydrocarbons (HC). Usually this type of gas sensor is large with a bulky metal casing to accommodate the optical path and the rotary device of the mechanical chopper; only few are compact.
As a result formaldehyde gas can build up in enclosed areas and, particularly when new furnishings or carpeting have been installed, it can pose a serious risk to health.

Non-dispersive infrared (NDIR) is a physical sensing technique that provides a number of advantages over catalytic gas sensing method.
The main feature of this technique is that fixed narrow-band filters are utilized with separate IR detectors to detect a few gas absorption lines across a.
A typical non-dispersive infrared (NDIR) detector passes a source of infrared energy through the sample and measures the energy received by one of two detectors.
The active detector responds to wavelengths in the same band as the sample gas, while the other detector measures a reference to compensate for changes within the instrument. When specific combustible gases are present, they. A large number of gases absorb infrared radiation by intramolecular vibrations.
For each specific material, the absorption intensity depends on the wavelength of the infrared radiation. This principle uses a non-dispersive infrared gas analyzer (NDIR gas analyzer) for gas analysis.
