  • Internal validation unit for QAL3 checks without the need for test gases
  • Lowest maintenance costs
  • High-resolution FTIR with long-life optical components
  • Pre-engineered based on > 25 years of experience
  • Internal validation unit – no need for bottled test gas for regular zero and span checks

Ability – Maintenance made easy with scalable digital solutions

  • Dynamic QR Codes for easy transfer of all relevant diagnostic information for faster troubleshooting and repair
  • Remote Assistance solution for expert on-demand service providing remote diagnostic and assistance for the analyzers
  • Condition Monitoring provides scheduled remote product health checks and generates reliable early warnings for recommended maintenance actions
  • Genix Datalyzer is cloud-based analyzer fleet health monitoring solution



ABB’s new ACF5000 is the specialist for emission and process monitoring from the pioneers in FTIR CEMS. It is available in the 4th generation. Since its introduction in 1993, ABB has sold more than 2000 units. The standard system design combines the advantages of a FTIR spectrometer, flame ionization (FID) technology, and oxygen measurement. The high-resolution FTIR spectrometer provides a selective measurement of infrared active gas molecules with high sensitivity and stability.

The multi-component analyzer system ACF5000 offers:

  • Simultaneous measurement of up to 15 gas components including all relevant pollutants
  • Proven hot/wet extractive measurement
  • Powerful FTIR technology for TOC
  • Complete system with a compact and modular design
    − Internal references − allow ongoing system validation
    − Lowest detection limits − suitable to monitor smallest emission limit values
  • One single sample inlet for all sample gases with a unique air-driven aspirator pump
  • Low cost of ownership
  • Communication, control, and maintenance via PROFIBUS, Modbus, TCP, and Ethernet (OPC)
