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.
Optical Analysis Description
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.
Advanced Technology & System Features
Optical system: Gold-coated multilayer mirrors for chemical and corrosion resistance.
Light source: SiC medium infrared with electronic stabilizer, extended lifespan.
Sample pretreatment: Built-in filtration unit for particulate removal.
Flexible software: Real-time monitoring, automatic calculation, and offline re-analysis.
Portable and robust: 20 kg, compact dimensions, easy for on-site deployment.
The instrument ensures high repeatability (<2% scale), low detection limits (<0.1 ppm), and fast response (T90: 120 s for 1 cm⁻¹ resolution), providing reliable data for industrial and environmental decision-making.
