Mixed Alkali Halide Dilution Matrices for Diffuse Reflectance Infrared Spectrometry: Effect of Particle Size

Abstract
Diffuse reflectance Fourier transform infrared spectra of coal diluted in two different alkali halide matrices were compared. Pure KBr and mixed CsI/KBr were tested for use as dilution matrices. When the variable of particle size was controlled, KBr was found to be the better diluent.
