One of the biggest advantages with using the MIR-FTIR is the ability to upgrade new gases and gas ranges to the gas library at any time.

The purchase of a complete continuous emission monitoring system is a significant investment. With the emissions limits tightening and new gases being introduced, plant operators need emission monitoring solutions that allows future upgrades.

Installed across the majority of the UK’s municipal waste incinerators, the MIR-FT CEM provides powerful gas measurement technology for the simultaneous measurement of multiple gases.

With heated Fourier Transform Infra-Red (FT-IR), the MIR-FT CEM has options to measure NH3, NO, NO2, NOx, N2O, CO, CO2, SO2, HCl, HF, CH4, H2O, O2 plus TOC with an additional FID analyser.



  • Designed for measurements of hot, wet and soluble sample gases
  • Future upgrades possible
  • Excellent calibration stability
  • Automatic spectral interference corrections
  • Fast and simultaneous measurements for multiple gases
  • Reproducible and accurate
  • Windows based PC driven software with on-board data acquisition
  • Capable of automatic QAL 3 checks when used in conjunction with IVIS unit
  • MCERTS Certified Emissions Analyser


The MIR-FTIR is an MCERTS certified emissions analyser which is designed to operate under Industrial Emissions Directive (IED) legislation. The MIR-FTIR is compliant with QAL 1 of EN14181 and automatic QAL 3 checks when used in conjunction with IVIS unit.

Dual Redundancy System

Under the IED, the maximum period allowed for any one episode of abatement or equipment failure must not exceed four hours. In addition, the total allowance period for a year must not exceed sixty hours.

The a1-cbiss duplex philosophy has therefore been specifically developed to assist you in complying with IED by reducing downtime, maximising availability and ensuring you achieve a sound return on your investment.


The MIR-FTIR is a 19″ rack mounted system, housed in air-conditioned enclosures.

Complete systems would normally comprise of:

  • Sample extraction and conditioning probe (with integrated temperature, pressure and flow measurement)
  • Heated sample lines
  •  Automatic calibration units
  •  Instrument Air drying system
  • CDAS Data Acquisition Software
