Particle size distribution with SEM

Particle size distribution (PSD) is determined from scanning electron microscope (SEM) images of around 300 particles.

Depending on the particle shapes, the method includes calculations on the diameters or lengths and widths of the particles. In addition to size, SEM provides qualitative information about surface morphology.

SEM is a good option for irregularly shaped and non-spherical particles such as fibers, rods, and crystals that cannot be characterized meaningfully with traditional methods, including laser diffraction (LD) and dynamic light scattering (DLS).

As a result of the analysis, SEM images and the determined particle size distribution for diameter (or length and width) are delivered.

Samples must be completely dry for SEM. If the particles are wet or dispersed in a solvent, the sample may be dried with a suitable sample preparation method before imaging. Ask the method expert for more information and a price for wet samples.
