Spectral Characteristics Dependent on ATR Crystal Selection- Differences in Properties (Shape, Hardness, Refractive Index) According to Sample -

ATR (Attenuated Total Reflectance) is a technique that is widely used in verification testing and contaminant analysis. With this technique, however, peak characteristics such as peak intensity and position, etc., vary depending on the shape of the sample and the type of crystal selected.
Here, using a variety of samples and three types of crystals (diamond, ZnSe, Ge), we conducted measurements and describe the typical ATR spectral characteristics associated with the contact status between the crystal and sample, as well as the shape of the sample.
