WebShivaji University, Kolhapur. You can use FT- IR spectroscopy in quantitative analysis. Select the band in the pretty empty region of the spectrum. Prepare different Conc. of the sample and ... 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 a… WebFTIR stands for Fourier Transform Infrared Spectroscopy. FTIR is a technology that can identify chemicals using an infrared light source to measure absorption. First, the sample is exposed to different wavelengths of infrared light and the instrument measures which wavelengths are absorbed. The computer takes that raw absorption data and ... heart pendant with picture inside
