Non-Dispersive Infrared (NDIR) Spectroscopy
Non-Dispersive Infrared (NDIR) Spectroscopy is a method of measuring the concentration of carbon oxides (CO and CO₂).
Typical gases in NDIR are nitrogen and zero air, which are used for purging, and gas mixtures for calibration.
Air Products' speciality gases have been specifically designed for the analytical user, and their equipment. By using the Experis® gases product range, ensures accuracy of results and equipment performance is optimised.

Business Development Specialist
"Which gases are commonly used for Non-Dispersive Infrared (NDIR) Spectroscopy?"
We recommend using Nitrogen BIP® or Argon BIP® as reference gasses because of the their low moisture specification (<0.02ppm) and low CO and CO2 specification (<0.5 ppm).
