Abstract (en)
[origin: WO2014079849A1] A method for characterising particles comprising the following steps: Producing at least one image of the particles of a sample with a scanning electron microscope, capturing and processing the image. The processing operation consists of: for each so-called usable particle, measuring the maximum Feret length and minimum Feret width of same; defining a geometric model of the particle from the maximum Feret length and minimum Feret width of same; calculating a projected area of the particle from the geometric model and the minimum Feret width of same; calculating a volume of the particle from the geometric model, the projected area and the maximum Feret length of same; calculating a characteristic particle size on the basis of the geometric model, the minimum Feret width and maximum Feret length; calculating a volume form factor from the volume and characteristic size.
