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. 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 dispersive spectrometer, which measures intensity over a narrow range of wavelengths at …

WebOct 9, 2024 · How does Fourier Transform Infrared Spectroscopy (FTIR) work? Light from an FTIR light source is split into two beams by a beam splitter (similar to a half mirror). One beam is transmitted to the moving mirror and the other beam is reflected by the fixed mirror. WebFourier Transform Infrared Spectroscopy, also known as FTIR Analysis or FTIR Spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some … solid polymer core
