NonDispersive Infrared (NDIR) Spectroscopy . NonDispersive Infrared (NDIR) spectroscopy is a measurement technique used to noninvasively detect gas concentrations. Depending on their molecular composition, polyatomic gases possess the ability to absorb electromagnetic radiation at specific wavelengths in the infrared region. NDIR spectroscopy utilizes this ability to determine the measured gas

Measuring Carbon Dioxide (CO ) Using NonDispersive ...
