WebAttenuated total reflectance (ATR) is a special accessory unit which can be used with Fourier transform infrared (FTIR) spectrometers. It enables … Webby transmission (upper spectrum) and by ATR (lower spectrum). The middle red spectrum is after ATR correction. The ATR correction feature of the FTIR software package will make a correction for the relative band intensity and its result will more closely resemble the transmission spectrum. Performing the ATR correction may also improve
The differences between FTIR, IR, and ATR-FTIR - Specac Ltd
WebFourier-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 … WebThe ATR spectrum of a substance will be different from the transmission spectrum, in which the light passes directly through the sample. The ATR technique changes spectra in two important ways relative to the transmission spectrum of the same substance. The depth of penetration of the evanescent wave is dependent on the wavelength of the light. smart electric scooter 12inches citycoco
