NDIR gas sensing: Improve you detector design

  • Hamamatsu Photonics Europe

Delve into the realm of non-dispersive infrared (NDIR) gas sensing and gain insights into its various limitations and solutions. Infrared spectroscopy, a method rooted in molecular vibrations, takes center stage. NDIR, born in the late 1930s, emerges as a key technology in identifying gases like CO, CO2, SO2, NOx, N2O, NH3, HCl, HF, and CH4.

However, despite NDIR sensors' stability and specificity, challenges like water absorption interference persist. This article unveils NDIR's fundamental principles, details sensor design nuances, and unveils strategies to overcome hurdles. Explore how our mid-IR LEDs and detectors illuminate the path to efficient and accurate gas detection.
