It performs qualitative and quantitative gas analysis via FTIR spectroscopy. Developed for environmental emergency monitoring, industrial emission inspection, leak detection and laboratory research, it provides rapid on-site testing of VOCs and inorganic hazardous gases. Complying with HJ 919-2017, HJ 920-2017 and HJ 1011-2018 environmental standards, it operates stably in off-grid remote field areas and surpasses traditional analyzers in sensitivity, measuring range and multi-component analysis capability.
The unit transmits infrared light through gas samples to capture molecule-specific absorption fingerprints. Fourier transform converts time-domain signals to frequency-domain spectra, delivering fast and accurate results for gas composition and concentration.
