Delft Solids Solutions is a contract research organisation founded in 2002. We provide unique expertise in powder and solids characterization via research & development, courses and seminars and consultancy. Our core activities include powder, particle and porosity characterization coupled to (bulk) solids behaviour. Such insights are applicable to a wide variety of powders, granules and other solid materials used in the various markets such as food, feed, pharma, cosmetics,
(petro-)chemicals, building materials, etc. A more detailed description of particle properties on the micro-level allows an improved understanding of the behaviour and control of solids on the macro-level.
A broad range of techniques and instruments including method development and consulting is available for bulk solids characterization: physical gas adsorption, chemical gas adsorption, mercury porosimetry, laser diffraction, photon correlation spectroscopy (PCS), sieving, helium pycnometry, microscopy. Besides investigation of these fundamental parameters, our laboratory infrastructure is also capable of measuring and correlating such properties with e.g. flowability, segregation, crushing strength, attrition, shear, and dustiness characteristics of powders, as well as caking and stickiness of powders depending on environmental conditions. In this way, a firm link can be established between the various physical properties of solids and their behaviour during processing, handling and application.
Information typically obtained comprises:
- Specific surface area (e.g. BET analysis)
- Porosity, pore volume, and pore size distribution
- Particle size and shape distribution
- Density (bulk, apparent, skeletal, tap)
- Flowability and hopper design
- Stickiness and caking
