Comparison of nanoaerosol sources and their applications. — •Svetlana Khasminskaya², Jan Meinen^{1, 2}, Markus Eritt², Andreas Comouth^{1, 2}, and Thomas Leisner^{1, 2} — ¹Karlsruhe Institute of Technology (KIT), Institute for Meteorology and Climate Research, Atmospheric Aerosol Research (IMK-AAF), Karlsruhe, Germany — ²Institute for Environmental Physics (IUP), Ruprecht-Karls-University, Heidelberg, Germany

A variety of sources for atmospheric aerosols in the nanometer range (electrospray ionization, microwave plasma reactor, atomizer and soot generator) are presented. Different materials, such as silicon oxides, iron oxides and soot, were tested with helium or air as carrier gas. The aerosol size distribution (SMPS, TEM, TOF, PMS) and the fraction of charged particles (Quartz Crystal Microbalance) are shown. The influence of different source parameters such as carrier gas and pressure and finally the applicability for laboratory experiments with atmospheric relevance and nano-toxicological topics is discussed.
