The Nicomp® DLS system effectively measures nanoparticle sizes both online in the process environment and in the lab.

The typical definition of a nanoparticle is a particle with a size between 1-100 nm. The term has been defined this way in both ISO standard 27687 and ASTM standard 2456-06. In the EU the definition is more clouded because of the wording used concerning that about 50% of the number distribution should be between 1-100 nm. Dynamic light scattering (DLS) remains the most popular particle size analysis technique for nanoparticles. The Nicomp® DLS system is used in many industries to measure the size of nanoparticles, both in the lab and online in the process environment.
