FT-IR Gas Analyzer for Stack Emissions & Multi-Gas Compliance Monitoring | IR850
FT-IR Gas Analyzer for Stack Emissions & Multi-Gas Compliance Monitoring | IR850
IR850 Mobile FT-IR Gas Analyzer
Portable multi-gas monitoring for organized emissions at fixed pollution sources — coal-fired power, steel, cement, waste-to-energy and chemical plants. Up to 50 gases per scan from a library of 300+ calibrated compounds, with ranges from ppm to percent.
One Portable System. 50 Gases per Scan. Results in Real Time.
The IR850 replaces multiple analyzers and complex sampling trains with one mobile FT-IR system that travels to the stack and measures on-site — inorganics, VOCs and greenhouse gases in a single scan — with documented accuracy for compliance, process control and emissions reduction.
What Problem Are You Solving?
Multiple Instruments, Lab Delays, Compliance Risk
- Grab samples sent to a lab — wait days for results
- Several portable analyzers needed for different gas classes
- Emission spikes missed between sampling intervals
- New gas requirement? Purchase additional hardware
All-in-One Portable Analysis, Immediate Results
- Complete mobile set: analyzer, full-heating sampling, rugged workstation in one transport case
- Up to 50 gases in one scan — inorganic, VOC, GHG
- Continuous monitoring at ≥5 scans/second — no gaps
- New gas requirement? Software library update — no hardware changes
Regulatory Frameworks Supported
Built for Emissions Compliance Worldwide
International
- US EPA Method 320 — FT-IR measurement of vapor-phase organic / inorganic emissions
- ASTM D6348 — Standard test method for gaseous compounds by FT-IR
- EN / ISO frameworks — automated monitoring of stationary-source emissions
China (HJ Series)
- GB / HJ standards — fixed-source emission monitoring methods
- VOC component monitoring — technical requirements for stationary sources
- Emergency monitoring — inorganic gases by portable FT-IR
Standard declarations available: EPA 320, ASTM D6348, GB/T. Formal certificates (e.g. MCERTS / HJ method validations) available on request — please confirm the exact certification scope required for your project when ordering.
Why Select the IR850?
True Portability, Real Performance
Engineered for field deployment: backpack-carried analyzer, full-heating sampling chain (≥180°C probe, 5m/1m heated lines), and rugged mobile workstation (i7 / 16GB / 1TB). Set up at any stack in minutes.
50 Gases per Scan, 300+ Library
From SO₂, NOₓ, CO, CO₂, NH₃, HCl, HF to benzene, toluene, xylene, formaldehyde and N₂O, CH₄ — measured simultaneously, ppm to percent. Concentration ranges expandable; custom gas configurations available.
Corrosive Environment Immunity
Anti-corrosion coatings on all gas-contact surfaces, a ≥180°C heated sample path, and three-stage (0.5–5 μm) filtration stand up to hot, humid, acid-laden flue gas from coal, cement and incineration.
Software That Works for You
Real-time multi-component display in ppm or mg/m³; automatic dry/wet correction; pressure & temperature compensation with interference correction; Excel export and one-click help files for service engineers.
From Stack to Report in Minutes
User-defined logging intervals, hourly/daily averages, concentration–time trend graphs and spectrum replay create complete audit trails for regulatory reporting.
Why FT-IR Wins for Portable Emissions Monitoring
Compared with Traditional Portable Methods
Electrochemical / NDIR / GC / Lab Sampling
- Electrochemical sensors: 3–6 gases only, cross-interference, calibration drift, short sensor life
- NDIR: one detector per gas, no VOC capability, limited dynamic range
- Portable GC: batch cycles of minutes, carrier-gas consumables, higher maintenance
- Lab sampling: transient events missed, transport contamination, results in days
IR850 Mobile FT-IR
- Up to 50 gases simultaneously — inorganic + VOC + GHG in a single scan
- Continuous real-time: ≥5 scans/second captures startups, upsets and shutdowns
- Self-contained: no carrier gas, no detector cooling (DTGS), heated sampling prevents condensation
- Field-rugged: corrosion-proof optics and triple filtration for acid gas and dust
Where Does the IR850 Excel?
SO₂, NO, NO₂, CO, CO₂ for emissions compliance; NH₃ slip from SCR/SNCR; N₂O greenhouse gas.
Why IR850: heated, corrosion-resistant sample path handles high-moisture coal flue gas.
Acid gases HCl, HF, SO₂; combustion verification with CO/CO₂; VOC surrogates for dioxin precursor screening.
Why IR850: triple filtration and acid-resistant coatings for corrosive, dusty flue gas.
Kiln and process optimization with NOₓ, SO₂, CO; alternative-fuel combustion monitoring.
Why IR850: built for abrasive dust and high temperatures that stall other portables.
VOC leak detection — BTX, olefins, aldehydes; process-safety gases such as HCN and phosgene.
Why IR850: 4 cm⁻¹ resolution (1 cm⁻¹ option) deconvolves overlapping spectra in complex mixtures.
Rapid deployment for accident investigation; ambient and fenceline monitoring around facilities.
Why IR850: portable set-up and broad-spectrum screening identify unknown contamination fast.
Relative-accuracy testing and stack surveys; Method 320 / ASTM D6348 equivalency demonstrations.
Why IR850: documented error performance (±5% rel.; ±3 μmol/mol abs.) supports defensible reporting.
