WebAn FT-IR Spectrometer is an instrument which acquires broadband NIR to FIR spectra. Unlike a dispersive instrument, i.e. grating monochromator or spectrograph, FT-IR Spectrometers collect all wavelengths simultaneously. This feature is called the Multiplex or Felgett Advantage. FT-IR Spectrometers are often simply called FTIRs. WebJan 30, 2024 · The O-H bond in the acid group absorbs between 2500 and 3300, the one in the chain between 3230 and 3550 cm -1. Taken together, that gives this immense trough covering the whole range from 2500 to … WebFTIR measures infrared intensity vs wavelength of light, and it is used to determine the functional groups present on the surface of the nanoparticles in the presence of protein, hydroxyl, carbonyl, ...
