Analyser of the size and potential of nanoparticles

The Malvern Zetasizer Nano ZS nanoparticle analyser enables the measurement of size, polydispersity, zeta potential and even particle mass of particles of sizes ranging from 30 to 1000 nm. The apparatus is used to characterise such materials as nanoparticles, colloids, proteins or micro-emulsions. It is used in the construction industry to assess the properties of emulsions, dispersion and to evaluate the stability of suspensions. In environmental protection, it enables the analysis of small nanoparticles that pollute waters and soil.
