FTIR Products Data Sheet

---

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:

Fourier Transform Infrared analyzer - 700 FTIR

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