Particle characterisation in the laboratory. The analysis of physical parameters relating to product development, quality control and process monitoring has become an integral component of the work performed by many laboratories. Recording the distribution characteristics of particle sizes and particle shapes of disperse systems is of central importance in this process as, in many cases, they significantly influence the final product characteristics, and product quality, as well as processing, transport and storage behaviour. Proven technologies in reliable measurement systems, featuring a modular structure that can be adapted to the needs of the samples to be investigated, provide reliable measurement results. Our sensors record and analyse interactions between particles and optical or visual waves, based on innovative technologies such as laser diffraction, dynamic image analysis, ultrasonic extinction, and dynamic light scattering. The measurement results are clearly prepared in distribution charts or tables, or as individual characteristic values, and very quickly provide the user with the information they need in terms of quality and process control.
