(a) Scope and frequency. If you measure CO using an NDIR analyzer, verify the amount of H 2 O and CO 2 interference after initial analyzer installation and after major maintenance. (b) Measurement principles. H 2 O and CO 2 can positively interfere with an NDIR analyzer by causing a response similar to CO. If the NDIR analyzer uses compensation algorithms that …

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas 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.

monitoring arose from the Environmental Protection Agency’s (EPA) Clean Air Act of 1970. This set a national goal to provide unpolluted air for all, and ultimately established a foundation for government and private industry pollution control. Due to development and urban sprawl, the original goal of the Clean Air Act has yet to be accomplished.
