Determination of Particle Size in Powders by Scatter Correction in Diffuse Near-Infrared Reflectance

摘要: Diffuse near-infrared reflectance spectroscopy has traditionally been an analytical technique for determining chemical compositions in a sample. We will, this paper, focus on light scattering effects and their ability to determine the mean particle sizes of powders. The data NaCl, broken glass, sorbitol powders are linearized submitted Multiplicative Scatter Correction (MSC), ensuing parameters used subsequent multivariate calibrations. results indicate that size can, large degree, be determined from NIR given type powder. Up 99% partical variance was explained by regression.
