Gas Analyzers

Fourier Transform Infrared (FTIR) Analyzers

CAI offers four analyzer models that utilize Fourier Transfer Infrared technology for measuring concentrations of multiple gases within 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 levels

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:

  • Stack gases (CEM/MACT)
  • Vehicle emissions
  • Process control
  • VOC abatement/scrubber efficiency
  • Ammonia slip
  • Gas purity
  • Agricultural emissions
  • Greenhouse gas
  • Biomass/landfill gas

FTIR Analyzer Highlights

  • Accurate analysis of IR-absorbing gases
  • Measure 20+ gases simultaneously
  • Low ppb to high % ranges
  • No Liquid Nitrogen required
  • Low acquisition and operating costs
