Research on the precise quantification of aerosols with optical aerosol spectrometers at high particle concentrations

Recently, Topas experts published an article on the topic of coincidence correction in the Journal of Aerosol Science. They present a correction method for the size distribution based on neural networks there. It is compared with the analytical correction method of Raasch and Umhauer from 1984. Especially at high concentrations, the new method provides a better correction result. More information is to be found in the article of the Journal of Aerosol Science. The publication of the scientific work and the associated expansion of our technical know-how make us proud and set another sign for our expertise in the field of aerosol and particle technology.
