Q.

What is FTIR?
A.
Fourier Transform Infrared (FT-IR) spectrometry is an instrumental method that permits simultaneous measurement of infrared absorption frequencies of chemical species in real time. The spectrometer functions by imparting a different modulation frequency to each individual infrared frequency or wavelength. The amplitude of each frequency detected is used to generate the infrared spectrum. Reduction in the amplitude at any specific frequency is the absorption due to a molecular species.
Q.

What applications use FTIR?
A.
PATI employs FTIR both in the lab and in the field. The lab uses FTIR for TDT Air Scan® analyses, off gas studies, and other special projects. Typical applications for the field (extractive FTIR) are stack emission compliance tests, relative accuracy test audits (RATAs), and engineering studies. We also routinely perform EPA Methods 320, 321, and 318.
