The production of nanomaterials requires extensive quality controls regarding the required product properties. In the case of spherical nanoparticles, the hydrodynamic diameter, the polydispersity and the surface charge of the particles play a fundamental role.
All nanoparticles produced by Senova are checked for the above properties with a Malvern Zetasizer Advance Ultra red label. The size determination is based on the measurement of dynamic light scattering (DLS) and the surface charge is determined by measuring the zeta potential. The measurements can be carried out for almost all types of nanomaterials and are particularly suitable for quality control with the data sheets we have prepared.
We gained our greatest experience with the measurement of nanomaterials. If you have other dispersions, for example from the food, dye or cosmetics industry, we can carry out preliminary tests for you in order to then plan the measurements using established protocols.
