Extractive (EXT) Fourier Transform Infrared (FTIR)

Spectrum Environmental Solutions' Extractive (FTIR) monitoring system, WaverunIR-EXT, is a multi-gas analyzer capable of part per billion to percent level sensitivity for virtually any gas (sans homonuclear diatomic species such as N2 , O2 , H2 , CI2 , I2 , and F2 ).

As a company dedicated to optical sensing measurements, WaverunIR-EXT can be customized to your particular need with respect to analytes of interest and sensitivity.

At the heart of our FTIR is the Thermo-Fisher interferometer, a research grade interferometer with superior stability due to its dynamic alignment feature.

Our scientists have used various FTIRs over our years in the industry and have chosen the quietest interferometer in the marketplace to integrate into the Spectrum FTIRs.
