Fourier-Transform Infrared Spectroscopy (FTIR) Systems for Advanced Gas Analysis
Detect, quantify, and analyze multiple gases in real-time with precision FTIR systems tailored for industrial and environmental applications.
Real-Time Emissions and Ambient Monitoring with FTIR Innovation
Fourier-Transform Infrared Spectroscopy (FTIR) is a powerful, non-destructive technique used to simultaneously measure multiple gases in real time. By analyzing how molecules absorb infrared light across a spectrum, FTIR systems provide detailed identification and quantification of a wide range of pollutants and compounds—including VOCs, CO, CO₂, NOₓ, SO₂, and hydrocarbons. This method is particularly well-suited for environments requiring high sensitivity and selectivity.
As a growing B2B provider across North America, Air Quality Instruments delivers FTIR-based systems that support regulatory compliance, operational efficiency, and environmental stewardship. Designed for both stationary and mobile deployment, our FTIR solutions offer dependable performance in applications ranging from continuous emissions monitoring to process control and ambient air analysis.
