Setup for production and characterization of molecular clusters from liquids — •Johannes Viehmann, Philip Wenzel, Andreas Hans, Rebecca Schaf, Arno Ehresmann, and André Knie — Institut für Physik and Center for Interdisciplinary Nanostructure Science and Technology (CINSaT), Universität Kassel, Heinrich-Plett-Straße 40, 34132 Kassel, Germany

In order to investigate real life processes within aqueous environments it is necessary to reconstruct natural systems of interest under laboratory conditions. Supersonic expansion is commonly used for the production of molecular clusters. Here we show how mass spectrometry enables us to adequatetly determine cluster sizes and characterize the parameter room of a cluster source. A setup for production and characterization of molecular clusters from liquids using a two chamber cluster source with integrated heating system is described.
