On-line FTIR analyser

The CX4000 is an extractive 19” rack-mounted FTIR gas analyser, typically used for continuous emissions monitoring for example in waste incineration and cement plants.

Gasmet CX4000 FTIR gas analysers are operated by an external industrial computer that operates Calcmet™ - software. Measurement results are stored on the computer and can be also transmitted through analog or digital outputs.

  • Simultaneous detection, identification and quantification of up to 50 different gas components
  • Possibility to re-analyze spectra
  • Modified classical least squares analysis principle


Sample cell heating (180°C) ensures even high water vapour concentrations or corrosive gases will not pose a problem.

The CX4000 can be equipped with a TDL (Tunable Diode Laser) module, which provides accurate measurement of Oxygen (O2). This makes the Cx-4000 the only gas analyser in the world to combine multicomponent FTIR gas analyser with a TDL in one enclosure.

The CX4000 has both TÜV (17th BlmSchV) and MCERTS certificates. The analyser is also compliant with U.S. EPA 40 CFR Part 60 Appendix b Performance Specification 15.

The CX4000 is an integral part of the Gasmet™ Continuous Emissions Measurement System (CEMS).
