Scope

The main technical content: The size, shape, surface characteristics, and other parameters of materials will significantly affect their physical and chemical properties, so it is necessary to conduct rigorous and accurate detection of the particle size of nanomaterials. Dynamic light scattering is a method of measuring the hydrodynamic particle size of nanoparticles and submicron particles, which is widely used in the particle size analysis of nanomaterials and is also an important aspect of nanomaterials research. The inter-laboratory comparison of particle size detection by dynamic light scattering instruments is an activity in which laboratories use such equipment to conduct particle size detection of nanoparticles and submicron particles. By comparing the differences between the measured values and the specified values, it is determined whether the participating laboratories need to pay attention to the reasons causing these differences. Therefore, it is very important to choose a suitable criterion for evaluating the results.
