This invention relates generally to the field of particle chromatography, and more specifically to a method and apparatus employing the cascade principle for the purpose of characterizing particles according to subtle differences between the individual particle contours, by passing the particles through a repetitive series of sieves in a column, that have the same mesh size and are dimensioned to pass the entire sample, and wherein the particle characterization is based upon resident time of the similarly shaped particles within the column.
