Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, the …

Capnography is a good example for NDIR spectroscopy, where the CO 2 concentration in the exhaled breath of a person is monitored over expired volume or time. By evaluating the five characteristics of a capnogram, , frequency, rhythm, height, baseline and shape, deductions about the health of the patient can be drawn. For this purpose, both a fast
Non-Dispersive Infrared (NDIR) technology is the most common method of measuring CO˚ in Indoor Air Quality analyses. The NDIR sensor consists of the following (see image below): 1) Infrared (IR) Lamp, 2) Gas Sample Chamber, 3) Wavelength Filter, and 4) an IR Detector.
