When the infrared light passes through the gas cell to be measured, these gas molecules have an absorption effect on the infrared light of a specific wavelength, and the absorption relationship obeys the Lambert-Beer absorption law. The infrared light emitted by the light source enters the gas cell through the GFC modulation wheel and is filled with The gas is absorbed by the bubbles of the gas to be measured, and all the way through the bubbles that do not contain the gas to be measured, the two paths of light are collected by the infrared detector after being converged by the lens, and the measurement signal and the reference signal are obtained after signal processing. By analyzing the two signals, the concentration of relevant components in the gas can be obtained.

Here are the key features and components of an NDIR-GFC gas analyzer:
- Non-Dispersive Infrared (NDIR) Spectroscopy: NDIR is a widely used technique for gas analysis. It relies on the absorption of infrared light by specific gas molecules. The analyzer emits infrared light at specific wavelengths that correspond to the absorption bands of the target gas molecules. The light passes through the gas sample, and the intensity of the transmitted light is measured by a detector. The concentration of the target gas is determined based on the amount of light absorbed.
- Gas Filter Correlation (GFC): GFC is a technique used to enhance the selectivity and sensitivity of NDIR measurements. It involves the use of gas filters that are designed to selectively absorb or attenuate specific wavelengths of infrared light. These filters are placed in the light path between the infrared source and the detector. By using multiple filters and correlating the signals, the interference from other gases or background noise can be minimized, improving the accuracy of the measurement.
- NDIR-GFC gas analyzers are commonly used for the measurement of gases like carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), and various hydrocarbons. They find applications in environmental monitoring, industrial processes, combustion analysis, and indoor air quality assessment. These analyzers offer accurate and reliable gas concentration measurements, helping to ensure safety, compliance, and process optimization in various industries.
