Fourier transform infrared spectroscopy (FTIR) is a fast, easy and reliable technique for material identification and quantification of constituents in a sample. Benefit from user-focused workflows and comprehensive FTIR performance in the lab and in the field with the Agilent FTIR spectrometer portfolio.

What is FTIR? FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. In infrared spectroscopy, IR radiation is passed through a sample. Some of the infrared radiation is absorbed by the sample and some of it is passed through (transmitted). The resulting spectrum represents the molecular

Try our 30 day free trial. We think you will prefer using Essential FTIR. FTIR spectra of polycrystalline samples of adenosine and uridine, pure and containing small (<10%) quantity of N (O)H or N (O)D groups, were measured in KBr pellets from 4000 to 400 cm (-1) at temperatures from 300 to 20 K. For the first time, the bands of narrow isotopically decoupled proton stretching vibration nu1 mode of NH- and OH- groups were 2009-06-10 FTIR. FT-IR (fourier-transform infrared) spectrometers are used to detect the composition of a sample by means of measuring its absorbance and reflectance of infrared waves.

There are many advantages to a Fourier Transform Infrared Spectrometer (FTIR): higher resolution at lower cost, relatively less time to collect spectra, for reacting systems the spectra are easier to interpret and FTIR can be used in a mode (photoacoustic) where samples do not have to be optically thin.
