WebHow does FTIR work? FTIR (Fourier transform infrared) is a common technique for measuring the infrared spectrum of a material. When infrared (IR) light passes through a sample, some of the radiation is absorbed. The pattern, or spectrum, of infrared light absorbed is unique to that chemical; it’s a molecular “fingerprint” that enables ... WebThe user simply places a sample directly into the infrared (IR) beam. As the IR beam passes through the sample, the transmitted energy is measured and a spectrum is generated. However, the analyst must often prepare the sample into a pellet, mull, film, etc. before the transmission measurement can be made. This requires expertise and can be ...
