The sizing of manufactured or naturally occurring materials is a useful tool which can isolate materials of a particular size, or confirm that particles are being created in a desired distribution.  The perimeter, shape, and aggregation patterning of particles are often of special interest.  Photometric particle size analysis performed by MicroVision Labs provides basics such as size distribution, max and min, and standard deviation, but also more complex information, such as aggregation, surface morphology, shapes and volumes.  Particle size analyses can be done on optical images or SEM images depending on the sample size and medium.  Many of our clients have commented on the value of actually being able to see the particles that we sized as well as receiving the statistical data in our PSA reports.
