WebHow FTIR Works. FTIR analysis measures the range of wavelengths in the infrared region that are absorbed by a material. This is accomplished through the application of infrared radiation (IR) to samples of a material. …. Then, the signal is decoded by applying a mathematical technique known as Fourier transformation. WebDuring the internal reflection, a part of the IR light travels into the sample, where it can be absorbed. This is called the evanescent wave. The penetration depth of the evanescent wave into the sample is defined by the refractive index …
