FT-IR8500 FT-IR Gas Analyzer

Description

FT-IR8500 is a purpose-built FT-IR gas analyzer for continuous on-line monitoring of flue gas, green gas and VOC emissions from fixed sources (coal‑fired power plants, steel mills, cement works, waste‑to‑energy and chemical plants). Covering 500–5000 cm⁻¹, it delivers ppm–% sensitivity, simultaneous quantification of up to 50 gases per scan, and calibrated models for 300+ compounds with expandable concentration ranges — new gases can be added without hardware changes. It ensure reliable, real-time performance in high-temperature, high-humidity and corrosive flue gas environments for compliance, process control and emissions reduction.

 Features

• DTGS detector, no cooling required
• Beam splitter: uses moisture-proof window material
• Wavenumber range : 500cm-1 to 5000cm-1
• Sample chamber heating temperature: not lower than 180℃
• Total optical path length should be no less than 4.5 meters
• Sample gas chamber volume should be less than 1.0 liter
• The inner walls of the sample gas chamber and the inner walls of the reflecting mirror have anti-corrosion coatings to prevent erosion by corrosive gases and can be used to measure gases with high temperature, high humidity, and strong corrosiveness
• Scanning frequency should be no less than 5 times/second
  
• Spectral resolution: 4cm-1 (standard), 1cm-1 (optional)

Software

• Real-Time Monitoring: The software displays key parameters, such as interferometer height, light source intensity, and sample chamber temperature.
• Multi-Component Analysis: Easily measure and display the concentrations of all target gases simultaneously
• Flexible Concentration Units: Adjust the gas concentration units to your preference (ppm, mg/m³).
• Dry/Wet Correction: Automatically convert between dry and wet concentrations based on your sample conditions.
• Data Logging & Reporting: Save measurement data at user-defined intervals (minutes or longer). Display hourly and daily average concentrations for each substance.
• Automatic Corrections: Pressure and temperature compensation ensure accurate measurements in varying environments. Built-in algorithms automatically correct for interferences between components.
• Continuous Data Recording: Enables continuous on-site data storage and automatic saving of measured spectra. Displays concentration vs. time trends for easy visualization. Previously saved spectra can be replayed for future analysis.
• Excel Export: Analysis results can be exported in Excel-compatible format for easy report generation.
• One-Click Help: A one-click function creates a help file that can be sent to service engineers for quick analysis of instrument status.
