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, 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. Specifically 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.
