Difference between atr and ftir
WebJan 6, 2024 · Obviously, the relative intensity difference between micro-FTIR and ATR-FTIR spectra for the band located at around 2900 cm −1 is ascribed to the different detection depth for these two techniques. At the stage of initiation and elongation, the primary wall was mainly composed of cellulose, waxes, pectins, and other noncellulosic … WebIn ATR FTIR spectroscopy the sample is in contact with the ATR crystal. The IR radiation travels through the crystal and interacts with the sample on the surface in contact with the ATR crystal. Because of the differences in refractive indices of both materials, total internal reflection occurs. This reflection forms the so-called “evanescent ...
