WebJan 30, 2024 · IR spectroscopy is very useful in the identification and structure analysis of a variety of substances, including both organic and inorganic compounds. It can also be used for both qualitative and quantitative analysis of complex mixtures of similar compounds. The use of infrared spectroscopy began in the 1950's by Wilbur Kaye. 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.

WebThe total scope of FTIR applications is extensive. Some of the more common applications are: Quality verification of incoming/outgoing materials. Deformulation of polymers, rubbers, and other materials through thermogravimetric infra-red (TGA-IR) or gas chromatography infra-red (GC-IR) analysis. Microanalysis of small sections of materials to ... WebFTIR spectroscopy uses modulated, mid-infrared energy to interrogate a sample. The infrared light is absorbed at specific frequencies directly related to the atom-to-atom vibrational bond energies in the molecule. When the bond energy of the vibration and the energy of mid-infrared light are equivalent, the bond can absorb that energy.
