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(FTIR) is used to detect changes of major functional groups of residual PS in frass (using, e.g.,Nicolet iS05 FTIR Spectrometer, Thermo Fisher Scientific, U.S.A.). 1. Prior to the analyses, the frass sample is lyophilized for at least 36 h to avoid deviation from water. 2. 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 "dispersive spectroscopy" technique, is to shine a monochromatic light beam at a sample, measure how much of the light is absorbed, and repeat for each different wave… list of cloud apps
