Attenuated total reflectance (ATR) is the most widely used sampling methodology for Fourier transform infrared (FTIR) spectroscopy. ATR-FTIR quickly and easily measures a broad range of sample types, including liquids, solids, powders, semisolids, and pastes.
WebMar 16, 2024 · Fourier transform methods are designed in such a way that they record the spectra in the time domain. The plot in Figure 4.3. 8 represents a particular wavelength or frequency of radiation in its time domain. What we observe in the time domain is the oscillation of the amplitude of the wave as a function of time. Figure 4.3. Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range. This confers a significant advantage over a … See more The goal of absorption spectroscopy techniques (FTIR, ultraviolet-visible ("UV-vis") spectroscopy, etc.) is to measure how much light a sample absorbs at each wavelength. The most straightforward way to do this, the … See more The interferogram has to be measured from zero path difference to a maximum length that depends on the resolution required. In practice the scan can be on either side of zero … See more There are three principal advantages for an FT spectrometer compared to a scanning (dispersive) spectrometer. 1.
