FTIR Spectroscopy: Attenuated Total Reflectance (ATR)

WebATR stands for attenuated total reflectance and is applied by pressing a crystal with a very fine tip on the sample. The Infared light is passing the crystal and interacts with the sample beneath it, yielding an IR spectra. It should be noted, that ATR produces high quality FT-IR data of almost any sample type without prior preparation. WebFTIR stands for “Fourier transform infrared” and it is the most common form of infrared spectroscopy. All infrared spectroscopies act on the principle that when infrared (IR) radiation passes through a sample, some of the radiation is absorbed. The radiation that passes through the sample is recorded. Because different molecules with their ...
