WebATR-FTIR Spectroscopy 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. Web2. INTRODUCTION Attenuated Total Reflectance (ATR) accessories remove the need for transmission cells and KBr pellets when performing measurements on liquid, semi-solid and solid materials. The ATR spectroscopy works especially well for opaque samples or samples that are too thick for transmission measurements.

WebFTIR Sample Techniques: Attenuated Total Reflection (ATR) How does it work? An ATR accessory operates by measuring the changes that occur in an internally reflected IR beam when the beam comes into contact with a sample. An IR beam is directed onto an optically dense crystal with a high refractive index at a certain angle.
WebIR reflective materials work best with this objective, while dark samples do not work as well. Figure 1. Optical configuration of a Cassegrain objective for reflectance.
