FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample. easy braid company

WebIntroduction The NIST Quantitative Infrared Database currently consists of a collection of absorption coefficient spectra of volatile organic compounds. These spectra were measured from primary gas standards prepared and verified at NIST. Spectra are provided in 5 resolutions from 2.00 cm −1 to 0.125 cm −1 using 5 apodization functions. WebPeak detection involves the identification of absorbance at specific wavenumbers in a spectrum, and is used for the qualitative and quantitative analysis of sample substances. With IRsolution, the threshold value, the noise level, and the minimum area are required as parameters for peak detection.
