The EasiDiff is an economical, high quality diffuse reflectance accessory designed to analyze a wide variety of solid samples. It is most often used in the analysis of pharmaceuticals, illicit drugs, inorganic solids and minerals, and powdered chemicals. The EasiDiff reduces the time required to produce an infrared spectrum compared to KBr pellet techniques. In general, diffuse reflectance is a sensitive IR sampling technique.
