Using air filters to see what aerosols are made of

Hello together. My Name is Denis Leppla and I am working at ATTO since 2017 with rather simple instruments for filter sampling. It consists of a filter holder to collect aerosol particles from the air on a certain other filter material. For that, it also needs a pump to pass air through the filter.  We then store the filters in a freezer until we bring them back to Germany. There we analyze them with a mass spectrometer at the Max Planck Institute for Chemistry in Mainz. With this analysis, we can get insights into the chemical composition of aerosol particles and identify hundreds of different compounds.
