FTIR Gas Analyser

An FTIR gas analyser is a specialised instrument performing Fourier transform infrared spectroscopy on gaseous samples enabling rapid identification and quantification of gas phase compounds. The gas-specific approach addresses applications requiring real-time gas composition monitoring.

The FTIR gas analyser architecture employs gas sampling cells with path lengths typically 2–10 metres enabling enhanced sensitivity through extended light-matter interaction. Infrared spectrometers measure light transmission through gas samples revealing molecular vibration patterns. Fourier transform algorithms convert measurements into spectral data enabling compound identification. Real-time processing provides immediate results.

Operational specifications include spectral resolution typically 0.5–4 cm⁻¹ enabling fine spectral features, sensitivity detecting ppm (parts per million) concentrations enabling trace gas detection, and response time <10 seconds enabling rapid monitoring. Automated data processing compares measurements against spectral libraries identifying compounds and quantifying concentrations.

Deployment applications include environmental monitoring detecting atmospheric pollutants or emissions, industrial process monitoring controlling combustion efficiency or emissions, and safety monitoring detecting toxic gas presence. Real-time monitoring enables rapid response to hazardous conditions.

Gas sampling systems include direct sampling from process streams, remote sampling through heated lines preventing condensation, and flow control systems optimising measurement conditions. Diverse sampling options address varied monitoring requirements.

Integration with alarm systems enables automated notification of hazardous conditions. Data archival enables compliance documentation and trend analysis.

Environmental operation across diverse conditions requires robust design preventing measurement interference.

In Pakistan, FTIR gas analysers support environmental monitoring and industrial operations.
