What does FTIR mean and how does the TruDefender use it?

Applies to: Chemical and Gas TruDefender FT (FTIR) | Tickets Solved: 0

FTIR stands for Fourier Transform Infrared Spectroscopy. FTIR is a technology that can identify chemicals using an infrared light source to measure absorption. First, the sample is exposed to different wavelengths of infrared light, and the TruDefender measures which wavelengths are absorbed. The computer takes that raw absorption data and conducts a math process known as the Fourier Transform to generate a readable absorbance spectrum. This spectrum can then be compared to a library of spectra to find a match. For a more detailed explanation, see the attached document.
