application of diffuse reflectance spectroscopy

Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) is a technique that collects and analyzes scattered IR energy. It is used for measurement of fine particles and powders, as well as rough surface (e.g., the interaction of a surfactant with the inner particle, the adsorption of molecules on the particle
Diffuse reflectance is an excellent sampling technique as it eliminates the time-consuming process of pressing pellets for transmission measurements. Diffuse reflectance can also be Diffuse reflective spectra showing greatly improved results from sample dilution. .Incident Radiation .Diffuse Reflection .Specular Reflection
The prerequisites for applicability of the Kubelka- Munk theor)) of diffuse reflectance for obtaining characteristic color curves qf powders are discussed, and some experimental support .for the theory is given. Methods are described for eliminating surface reflection, which is alwa.vs superimposed upon the diJuse reflection
