    Abstract

    Particle size distribution is vitally important in pharmaceutical formulation. Spectroscopy is the most prominent method for in-line particle measurements and process analytics, and near-infrared (NIR) spectroscopy can be seen as the workhorse in the field of Process Analytical Technology (PAT). This article considers analysis using an innovative spatially and angularly resolved diffuse reflectance measurement (SAR-DRM).
