Particle size analysis

Particle size analysis is, as the name suggests, the size analysis of nanoparticles. A nanoparticle can measure between 1 and 100nanometeres. The smallest difference in diameter determines the application and therefore a particle size analysis is crucial.

Laser diffraction, particle size zeta potential molecular weight and microscope image analysis are the most common techniques to analyze the particle’s size.

    Together with international partners, researchers at Graz University of Technology have developed a measurement method that measures particles below 10 nanometres for the first time and will contribute to the implementation of future, stricter emission standards. A few days ago, the European Commission presented its Green Deal, which aims to make the EU climate neutral by 2050 in order to protect the environment and improve people's health and quality of life. One of the planned measures is the introduction of stricter exhaust regulations. The limit values for pollutant emissions from vehicles have already been laid down by law.
