WebAttenuated total reflectance or ATR is, along with transmission, one of the most common sampling techniques in Fourier transform infrared (FTIR) spectroscopy. ATR is based on total internal reflection where infrared (IR) light and sample interact only at the point where IR light is reflected. Transmission, on the other hand, is based on IR ... WebFourier-transform infrared (FTIR) spectroscopy is one of the most versatile analytical tools used across various disciplines. In this study, the Thermo Scientific™ Nicolet™ iS10 and Nicolet iS50 FTIR Spectrometers, equipped with attenuated total reflection (ATR) FTIR and transmission FTIR, were used for the determination of protein
