Fourier Transform Infrared (FTIR) Spectroscopy

CleanAir has the capability to perform Fourier Transform Infrared (FTIR) Spectroscopy for the analysis of various gaseous emissions from stationary sources. The test methods using FTIR for analysis are Method 320 and 321. We have the necessary field experience with the FTIR as well as the knowledge and skill to create new FTIR standards, test protocols and methods.

Method 320

This method determines compound-specific concentrations in a multi-component vapor phase sample in a closed-path gas cell. Specifically, these are organic or inorganic compounds which absorb energy in the mid-infrared spectral region (about 400 to 4000 cm-1). A computer program is used to analyze infrared spectra and report compound concentrations.

Method 321

This method determines hydrogen chloride (HCl) concentrations in a multi-component vapor phase sample in a closed-path gas cell. These are inorganic compounds which absorb energy in the mid-infrared spectral region (about 400 to 4000 cm-1). Computer software is used to analyze infrared spectra and report HCl concentrations.
