Portable FTIR Gas Analyzer for Multi-Gas Environmental & Industrial Monitoring

High-Performance Portable FTIR Gas Analyzer

The portable FTIR gas analyzer is a cutting-edge solution for real-time multi-gas detection and analysis. Using Fourier Transform Infrared spectroscopy (FTIR) and full-spectrum analysis technology, it can detect thousands of organic and inorganic gases and quantify hundreds of compounds simultaneously.

Key features include:

  • High-resolution analysis: 1 cm⁻¹ resolution (adjustable scan speed) for precise qualitative and quantitative measurement.

  • Wide spectral range: 485–8500 cm⁻¹ for broad gas coverage.

  • High-performance DTGS detector: Operates at room temperature, no refrigeration needed, long lifespan, wide linearity, and high sensitivity.

  • Long-life reference laser: Solid-state VSECL laser with up to 10 years of service.

  • Built-in zirconia sensor: Measures oxygen in the sample gas accurately.

  • Advanced sample handling: 300 ml gas chamber with nitrogen reverse purge interface and backblown design to minimize contamination.

  • Software integration: PLS algorithm for robust qualitative and quantitative analysis, real-time data recording, and Excel-compatible export for offline processing.

This analyzer is ideal for industrial emission monitoring, environmental compliance testing, CEMS comparison, boiler and combustion monitoring, and emergency air quality assessment.

Multi-Gas Detection & Industrial Applications

The portable FTIR gas analyzer supports simultaneous detection of more than 50 gas components, including:

SO₂, NO, NO₂, CO, CO₂, NH₃, HCl, HCN, HF, H₂O, CH₄, C₂H₆, C₃H₈, C₂H₄, HCHO, C₆H₆, C₇H₈, C₂H₂, and more.

Its modular design and embedded control system allow flexible deployment in various scenarios:

  • Fixed pollution sources: industrial stacks, incinerators, boiler flue gas

  • Environmental monitoring: air quality, VOC detection, emergency pollution events

  • Laboratory analysis: gas purity testing, research and development

Optional external modules, such as H₂S detection, further extend its applicability, ensuring users can tailor the system to specific industrial and environmental compliance needs.
