Solids Solutions: expert in powder and particle characterisation

In the world of powders and finely divided materials, particle behaviour is crucial for product quality and processability. Whether it is pharmaceutical tablets, food or technical powders, accurate analysis is essential. This is where Solids Solutions comes in. This leading Delft-based company specialises in the characterisation of powders, particles and granules, helping companies worldwide improve product quality and process optimisation. In this article, we dive into Solids Solutions’ expertise and discuss two key topics within their field of work: powder flow analysis and powder clumping.

What does Solids Solutions do?

Solids Solutions has been operating as a specialist knowledge centre and service provider in the field of solids since 2001. The company focuses on analysing, optimising and understanding physical properties of powders, granules and particles. Solids Solutions’ services range from laboratory research and consultancy to advanced training programmes for professionals from industries such as pharmaceuticals, chemicals, food and materials science.

What makes Solids Solutions unique is their multidisciplinary approach and use of advanced analytical techniques. Clients not only get data, but also in-depth advice on how to use that data to improve processes or solve problems.

Powder flow analyser: getting a grip on the flow

One of the most valuable tools used by Solids Solutions is the powder flow analyser. This device measures the flow properties of powders under controlled conditions. The way a powder flows is very important for applications such as filling, mixing and conveying. Poor flow can lead to blockages, irregular dosing or even production errors.

Solids Solutions uses the FT4 Powder Rheometer and Ring Shear Testers, among others, to determine flow properties. These measuring instruments analyse cohesion, flow resistance, energy consumption and compression behaviour of powders, among other things. Based on this data, production processes can be optimised and blends can be adjusted to achieve more consistent results.

Powder caking: more than an annoying side issue

Powder caking is a common problem within various industries. When powder particles stick together and clump together, it affects not only the flow, but also the solubility, mixability and dosage of the product. Think, for example, of instant coffee that does not dissolve properly, or pharmaceutical products that are unevenly distributed.

Solids Solutions investigates the causes of powder clumping using such methods as moisture absorption analyses (DVS), particle size distribution, and surface characterisation. By identifying factors such as moisture, temperature, surface tension and particle shape, targeted recommendations can be made to minimise or even prevent clumping. This leads to higher product quality and production process reliability.

Application in practice

Solids Solutions’ knowledge and techniques are used daily to help companies with a variety of challenges. From improving powder filling machines to developing new powder formulations, each project is approached with precision and customisation. In addition, the company regularly organises seminars, workshops and courses, allowing customers to raise their level of knowledge internally as well.
