Understanding the structural and chemical properties of particles in the atmosphere is critical because of their health effects and their influence on the earth’s radiative situation, and hence on our climate. In this respect, advanced electron microscopy plays a key role for studying particle composition, chemistry, morphology, phase and internal structure.
Immunogold-labelled SEM analysis of allergens
In the last decades, the number of people with allergies against at least one of the major allergens like birch, grass, ragweed pollen, or domestic cat has been steadily increasing. An advanced method to localise specific proteins which are responsible for an allergic reaction is scanning electron microscopy with immunogold labelling.
TEM analysis of asbestos fibres
Rough asbestos mesurements are performed in the light microscope, but the unambigous identification of asbestos fibres is only possible by the means of transmission electron microscopy (TEM), electron diffraction (SAED) and x-ray spectroscopy.
SEM analysis of aerosol particles
High resolution scanning electron microscopy (SEM) contribute to a better understanding and the solution of many problems in environmental research, earth sciences and vulcanology. The morphology and the chemical composition of atmospheric areosol particles considerable influence the climate, hence our every day life.
TEM analysis of diesel exhaust particles
Diesel particulate emissions are a major source of fine and ultrafine atmospheric particles. These particles are of great interest because of their unfavourable health effects and their impact on the earth’s atmosphere. Since diesel particles are structurally complex, a detailed knowledge of their size, morphology and chemistry is needed which can only be achieved via TEM analyses.
