Specialist in particle technology

Do you work with particles and powders and need information about certain properties? Then Solids Solutions can help you with that. We have over 40 years of experience in the field of powder and particle technology. In our laboratory in Delft we do extensive research on this subject, in order to gain insight into the properties of particles. In this way, more knowledge is gained about their application in products from various industries. This enables us to find a solution if you get stuck in the process of product development. We also share our knowledge with you through courses, seminars and presentations.


Sedimentation nanoparticles

The particles that Solids Solutions investigates vary greatly in shape and size. Specific properties of the particles ensure that they can be used for various purposes. Nanoparticles are so small that they have hardly any mutual attraction or thermal movement. As a result, they can be used to mix substances that normally do not mix well. Various methods can be used to measure the size of nanoparticles. One is sedimentation nanoparticles, whereby the size can be determined from the sedimentation rate in a liquid. Subsequently, the particle mass, which is determined by the particle size and density, can be correlated to this speed.

Dynamic light scattering


To be able to characterise the particles of powders and suspensions, laser diffraction is often used. In this process, particles are scattered and illuminated with a laser beam, and the scattering pattern is analysed. This method is also called dynamic light scattering. With this method, the particle size and particle size distribution can be determined. The scattering pattern depends on various factors, such as the size of the particles, but also on the material, the surface roughness and the medium in which the particles are located. If you want to know whether we can help you with the development of a product, please contact us so we can discuss the possibilities and give you more information about dynamic light scattering of nanoparticles.
