Do you need information about the specific properties of certain particles? Then Solids Solutions can help you. In our laboratory in Delft, we conduct research on particles and powders. These are used in various industrial products, from medicine and food to building materials. The properties of the particles are decisive for the functioning of the product. If you get stuck in the production process, we can identify the cause and advise on a suitable solution.
Sedimentation of nanoparticles
The size of particles can be determined from the settling velocity of the particles in a liquid. This is correlated to the mass of the particles using Stokes’ Law. In the case of sedimentation nanoparticles, X-rays are used to measure the settling of the particles in certain time intervals. The particle size distribution can thus be determined in a relatively short period of time. Various other methods are also available in our laboratory to investigate the properties of particles. The method we use depends on the substance to be examined and the information to be obtained.
Dynamic light scattering
To measure the particle size of powder particles, we use dynamic light scattering. The powder is scattered in a certain medium, after which the particles are illuminated by a laser beam. Based on the scattering pattern, the particle size and particle size distribution can be calculated.
Would you like to gain specific knowledge in the field of particle and powder technology? Solids Solutions regularly organises seminars, workshops and presentations on various topics in this field. In addition, we have a knowledge base with publications of our research. You can request these in our online knowledge centre to view for yourself. Can we help you with the development of a product?
