When the infrared light passes through the gas chamber, the gas molecules have an absorption effect on the infrared light with a specific wavelength. Meanwhile, 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. Next, the measured bubbles of the gas absorb the gas. Then, the infrared detector collects two signals of the light after the lens converges the light. Finally,  obtain the measurement signal and the reference signal after signal processing. By analyzing the two signals,  obtain the concentration of relevant components in the gas.

Here are the key features and components of an NDIR-GFC gas analyzer:

  1. 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.</span>
  2. 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.
  3. 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.

Measuring carbon dioxide (CO2) is important for understanding the role it plays in the environment and its effect on climate change. CO2 is a major component of Earth’s atmosphere, and it traps heat like a blanket, causing global temperatures to rise. Too m uch CO2 can lead to drastic changes in our weather patterns and ecosystems, so monitoring its levels is essential for predicting future climate conditions. Additionally, measuring CO2 can help us better understand our impact on the environment and make informed decisions about how to reduce emissions and slow down down down down down global warming. By analyzing CO2 data over time, we can develop strategies to mitigate the effects of climate change and ensure a sustainable future.

Before industrialization, the global average annual atmospheric carbon dioxide concentration was 278ppm (1ppm is one part per million). In 2012, the global annual average atmospheric carbon dioxide concentration was 393.1ppm. By April 2014 , the monthly average carbon dioxide concentration in the northern hemisphere atmosphere exceeded 400ppm for the first time. . 2. Global climate warming, the continuous aggravation of the atmospheric greenhouse effect leads to global climate warming, resulting in a series of global climate problems that cannot be predicted by today’s science. According to the International Climate Change Economics Report, if human beings maintain the current way of life, by 2100, there will be a 50% chance that the global average temperature will rise by 4°C.
