Universal ATR Sampling Accessory User’s Guide . 5
Introduction
The Universal Attenuated Total Reflectance Accessory (UATR) is an internal reflection
accessory, used with a Spectrum Two Series spectrometer, for simplifying the analysis of
solids, powders, pastes, gels and liquids. The technique is non-destructive.
As the beam does not penetrate deeply into the sample, this technique is ideal for analyzing
strong infrared absorbing solutions, such as emulsions or aqueous solutions. The technique
can also prove useful in measuring homogeneous solid samples, solid surfaces and coatings
on solid samples.
