![]() These are determined as one would with a caliper: by measuring the distance between parallel tangents. Feret diameters, for example, can be specified to describe the various dimensions. By analyzing individual particle images, both shape and size are measured. With the static method, the particles are at rest during the measurement (as with a microscope) with dynamic image analysis, moving particles are analyzed, either in a liquid, in an air stream or in free fall. A distinction is made between particle measurement with Dynamic Image Analysis and Static Image Analysis. Imaging techniques for particle measurement offer a number of advantages. Our experts will be happy to assist finding the right solution for your application. With an extensive understanding of the strengths and weaknesses of each method, Microtrac offers an unrivalled product range of technologies for particle measurement. Since the result of a particle measurement depends on how "size" is defined, there is often confusion in the interpretation of the measurement results. In all possible measuring directions, the same result is obtained.įor non-spherical particles, however, the result of the particle measurement depends both on the orientation of the particles during the measurement process and on the peculiarities of the method used. Particle measurement with these different methods leads to different results, because the "size" of particles can be interpreted quite differently: Size is unambiguously defined only for spherical particles (diameter = particle size). These include laser diffraction, image analysis, dynamic light scattering as well as sieve analysis.
