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. The technique gives information about the surface properties and condition of materials and can be useful for both qualitative and quantitative measurements.
This Perkin Elmer universal ATR sampling accessory is in good shape.
A 90 day warranty is included.
