Attenuated Total Reflectance
A reflectance sampling technique, used in such accessories as the Golden Gate and the Benchmark 6 Reflection ATR System. A beam of Infrared radiation is passed through a prism of material which is Infrared transparent, and has a high refractive index, at least higher than the sample being analyzed. Due to internal reflectance, the light reflects off the surface of the crystal at least once, setting up an evanescent wave, which extends into the sample by typically a few microns. The sample must be held in intimate contact with the crystal.

Diffuse Reflection
The random reflection resulting when a beam of light reflects off a rough, matt surface e.g. powder or fiber.
Specular Reflectance
The reflectance occurring when a beam of light strikes a smooth, shiny surface, e.g. a mirror, such that the angle of incidence equals the angle of reflection.
Transmission
A physical phenomenon where radiation passes through a body. When producing a transmission spectrum a proportion of the energy is absorbed by the sample, while the remainder travels on to the detector.
Extreme Conditions
A variety of products offering different techniques that can be used at high or low temperatures together with high or vacuum pressures. Please contact us to discuss your requirements.
Gas Cells
Our comprehensive range of FT-IR and process gas cells covers every conceivable analytical need, whether it be in the laboratory, the field or on the plant.
