Abstract Viral aerosol is characterized by its small size and can result in adverse health effects. Some viral aerosol such as Influenza virus can pose serious threat to human health. However, sampling viral aerosol is difficult due to its small size. One effective method for sampling sub-micron aerosol is through aerosol condensation growth. The Steam Jet Aerosol Collector (SJAC) uses the condensation growth method for particle collection, and was applied to viral aerosol sampling for the first time. Another advantage of the SJAC is the ability to collect aerosol in aqueous samples, which enable real time detection of biological agents. MS2 bacteriophage was used as the test aerosol and we searched for the SJAC’s optimum operation parameter settings. We will report how different solvent vapor and temperatures affect the viability, condensation growth, and collection efficiency of MS2 bacteriophage when using the SJAC. The experimental result can facilitate our understating of how different solvents affects the condensation growth of viral aerosol and improve our understanding of infectious viral aerosol.
