Short summary
The collection between aerosol and a water droplet is an important mechanism for removing particles from the atmosphere, and has an influence on cloud dynamics, precipitation processes and cloud lifetime. In this experiment, the collection process was studied on a single-droplet basis, with atmospherically relevant conditions (droplet sizes, charges and flow). Collection efficiency values were found to be in agreement with previous experimental and theoretical studies.
