Short summary
We present a comprehensive characterization of a commonly used commercial instrument (WIBS) for the real-time detection of fluorescent bioaerosols and suggest improved analysis and threshold strategies. Summaries of both biological and potential interfering, non-biological particles (70 aerosol types in total) are discussed in detail. The strategies we suggest will minimize interference from non-biological particles and will aid instrument users’ interpretation of ambient particle data.
