Short summary
We report experimental measurements of particle formation in a flow reactor that extend the results from this experiment to a total of more than 270 runs over a time period of ~3 years. This has allowed us to detect a general increase in the cleanliness of the system and improve our knowledge of its chemistry. In-house simulations allowed us to construct phenomenological free energies of molecular clusters of sulfuric acid and ammonia that are appropriate for application to the atmosphere.
