In... WebMar 16, 2024 · Whereas a conventional scanning spectrophotometer that uses a monochromator takes several minutes to scan through the wavelengths, the mirror movement in an FT-IR occurs over a few seconds. Another advantage is that an FT-IR has no slits and therefore has a high throughput of radiation.

In every scan, all source radiation goes through the sample. The interferometer is a fundamentally different piece of equipment than the monochromator found in UV/Vis spectrometers.
WebFTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample. 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 ...
