Dynamic Collimation Open Path Infrared Spectroscopy Monitoring System for Pollutant Gases

Most industrial emissions contain pollutant gases with distinctive infrared fingerprints, making infrared spectroscopy highly effective for continuous and automated online measurement of various gas components. The open path Fourier Transform Infrared Spectroscopy (FTIR) technology utilizes an open measurement approach, allowing the light path to traverse the pollution area. Its non-contact and sampling-free operation mode is ideal for monitoring gas pollutants, especially volatile organic compounds (VOCs), from diffuse sources. This product is built on a high-performance dynamic collimation infrared interferometer and employs either a transmittance or reflection setup to achieve continuous automated online measurements of pollutant gases in open environments, fully harnessing FTIR technology's advantages in measurement range, signal-to-noise ratio, and spectral resolution.

This system is based on the principles of Fourier Transform Infrared Spectroscopy and utilizes a high-performance, compact infrared interferometer, combined with a compact multi-reflection cell and low-noise signal detection unit. It can accurately analyze pollutant gases from ppb to ppm levels. This analyzer is suitable for emergency monitoring of chemical gas emissions and leaks during sudden pollution incidents, enabling rapid assessment of contamination levels. The system excels in key performance metrics such as spectral resolution, measurement speed, analyzable species, weight, and volume. Its specially designed interferometer structure offers excellent vibration resistance and can be mounted on various mobile platforms.





Fourier Transform Infrared Remote Sensing Imaging System for Gas Leakage

The system is based on the principle of Fourier transform infrared spectroscopy, using a high-performance, lightweight infrared interferometer, combined with a compact multi-reflection pool and a low-noise signal detection unit, which can accurately analyze pollutant gases at the ppb to ppm level. It can be used for emergency monitoring of industrial gas emissions and leaks, quickly obtaining the pollution status. The system has significant advantages in spectral resolution, measurement speed, variety of analyzable components, weight, volume, and other core indicators. The specially designed interferometer structure has excellent anti-vibration performance and can be connected to various mobile platforms.




Total Pollution Gas Infrared Solar Occultation Ground-based Survey System (SOF-FTIR)

Harmful gas emissions from industrial pollution sources are one of the main contributors to atmospheric pollution. The infrared solar occultation flux measurement technology measures the solar absorption spectrum around pollution source facilities, allowing for rapid and accurate assessment of gas emissions when combined with meteorological data. This method facilitates the measurement of emissions from various elevated point sources such as petrochemical plants, power plants, and steel mills, as well as from unorganized emission surface sources and regional pollution rates. Additionally, it can operate in a fixed-point mode for comprehensive observations of greenhouse gas totals across entire layers. Currently, the product is undergoing targeted modifications to become the only domestically-produced Fourier Transform Infrared Spectroscopy detection system. It will participate in key observations of regional and vertical distribution characteristics of essential atmospheric components in the Arctic, providing scientific evidence and technical support for understanding the rapid change mechanisms of Arctic atmospheric elements.
