A nano particle size analyzer is used to determine the size of individual particles as well as a size distribution range for a given sample. The pharmaceutical industry uses nano particle size analyzers because the size and shape of a particle can affect how a medication works in the body. Nano particle size analyzers can measure particles in many ways, including light scattering, laser diffraction, photon correlation spectroscopy, and sedimentation. The first three methods work by watching how light or lasers are shifted due to the particles and sedimentation determines particle size by measuring how fast the particles fall to the bottom of the sample. Some features to look for in nano particle size analyzers include the ability to process wet and/or dry dispersions; the particle size range that can be measured; whether it can determine shape as well as size; and whether it can measure concentration, zeta potential, and aggregation.
