NDIR (Non-Dispersive InfraRed) Analysis

This method of detection is based on the Luft detector. By passing infrared energy through a cavity of two cells (reference & measuring) to a non-linear detector (the Luft detector), the measurement is based on the difference in response of the detector with the gas-of-interest present in the cavity versus its response with no gas of interest in the cavity. The higher the difference, the higher the concentration of the gas-of-interest.
