High-volume sampler for size-selective sampling of bioaerosols including viruses.

ABSTRACT: Owing to the recent global spread of the new coronavirus SARS-CoV-2, the development of technology to effectively detect viruses in crowded public places is urgently needed. In this study, a three-stage high-volume bioaerosol sampler was developed for the size-selective sampling of bioaerosols through the suction of air at a high flow rate of 1000 L/min. In stage 1, an omnidirectional inlet cyclone separator that can draw air from all directions was applied to collect bioaerosols larger than 10 μm in the collection fluid. In stage 2, an axial flow cyclone separator was used to collect bioaerosols sized between 2.5 and 10 μm in the collection fluid. In stage 3, bioaerosols smaller than 2.5 μm were collected on a filter and extracted in a solution through an elution process using a sodium ph
