Ftir Sampling Techniques Attenuated Total Reflectance Data Collection Attenuated total reflectance (atr) is a sampling methodology that enables the direct examination of solid or liquid samples without further preparation. it utilizes total internal reflection to generate an evanescent wave that penetrates the sample, providing valuable molecular information. Attenuated total reflectance (atr) is the most widely used sampling methodology for fourier transform infrared (ftir) spectroscopy. atr ftir quickly and easily measures a broad range of sample types, including liquids, solids, powders, semisolids, and pastes.
Figure 1 Ftir In Reflectance And Attenuated Total Attenuated total reflectance (atr) has become the primary sampling method for ftir spectroscopy. the major advantage of atr is the lack of sample preparation for liquid and solid samples. In this first part, we’ll learn the basics of atr spectroscopy. in the second, we’ll learn how to calculate the effective depth of penetration for atr, and in the third, we’ll discuss some of the practical implications of different atr puck choices for the quest atr accessory. The technique of attenuated total reflectance (atr) has in recent years revolutionized solid and liquid sample analyses because it combats the most challenging aspects of infrared analyses, namely sample preparation and spectral reproducibility. Such spectra are called internal reflection spectra or attenuated total reflection (atr) spectra. atr is the most commonly accepted descriptor for this spectral collection technique.

There are several ftir sampling techniques available, with the most common being transmission, attenuated total reflectance (atr), specular reflectance and diffuse reflectance. Atr ftir spectroscopy is defined as a technique that utilizes attenuated total reflectance geometry to measure infrared absorption by a sample in contact with a reflecting surface, allowing for the analysis of solid state forms and host–guest interactions without the need for sample preparation. This module will cover the basic experimental set up that is currently being utilized in research, briefly go over essential equations that will help the reader better understand methods of experimentation, and finally provide an example of how atr ftir can be utilized. At a high level, atr simply involves directing light through a crystal to the sample being investigated. the light interacts with the sample, passes through the crystal again, and is then detected. but let’s dig a little deeper into what is going on during this process.
