Here you will find information about particles in the air or in settled dust from various work environments.
The images show the morphology, surface structure, and size of the particles, while the X-ray spectra provide information about chemical composition. In addition, a brief description is given of important features and characteristics and the possible sources of the particles.
Why a particle atlas?
Characterization and identification of particles in an aerosol are important for several reasons. Size determines where in the respiratory tract the particles are deposited. Information on chemical composition and morphology makes it possible to identify the particles and thus assess their potential health risks upon inhalation. Identification of particles can also indicate sources of pollution and is therefore important for preventive measures.
Characterization and quantification of particles are often time-consuming. To facilitate this work, our electron microscope is equipped with automated analysis equipment. The images and analyses in the database were produced on a Jeol JSM‑6400 SEM with a ThermoNoran Vantage DSI EDS system. With this equipment and skilled professionals with many years of experience in particle identification from various work environments, we have established extensive knowledge about aerosols. This information has been compiled in a database that we are pleased to make available to customers and partners through our particle atlas.
