CAI-FTIR (Fourier Transform Infrared Spectroscopy)

CAI offers four analyzer models that use Fourier Transfer Infrared Technology to measure concentrations of multiple gases in a sample. CAI FTIR analyzers deliver fast, accurate analysis of virtually any gas that has an infrared absorption spectrum.

  • 600 SC FTIR – Most IR absorbing gases + short cell for higher concentration levels
  • 700 FTIR – Most IR absorbing gases at ppb and low ppm levels
  • 7000 FTIR – Most IR absorbing gases at ppb and low-ppm level


CAI FTIR analyzers are based on Fourier Transform Infrared Spectroscopy. Non-symmetrical gas-phase molecules absorb IR light, causing the molecular bonds to stretch, bend or rotate. This absorption is used to measure and quantify several chemical components simultaneously. CAI FTIR analyzers are well suited for a wide range of applications, including:

  • Flue gases (CEM / MACT)
  • Vehicle emissions
  • Process control
  • VOC reduction / scrubber efficiency
  • Ammonia sanding
  • Gas purity
  • Agricultural emissions
  • Greenhouse gas
  • Biomass / landfill gas
  • Pharmaceutical industry


FTIR Analyzer Highlights

  • Accurate analysis of IR absorbing gases
  • Measure 20+ gases simultaneously
  • Low ppb to high % range
  • No liquid nitrogen required
  • Low acquisition and operating costs
