ABSTRACT:
Methods, systems and computer readable media for computing small particle size distributions. A reference matrix of pre-computed reference vectors is provided, with each reference vector representing a discrete particle size or particle size range of a particle size distribution of particles contained in a dilute colloid. A measurement vector of measured extinction values of a sample dilute colloid is provided, wherein the measured extinction values have been measured by spectrophotometric measurement at the discrete wavelengths. Size distribution and concentrations of particles in the sample dilute colloid are determined using linear equations, the reference matrix and the reference vector.
