Detection of Suspended SARS-CoV-2 in Indoor Air Using an Electrostatic Sampler
A prototype virus sampler using electrostatic precipitation has been developed to investigate aerosol infection by SARS-CoV-2. The sampler consists of a discharge electrode placed inside a vial, and a thin layer of viral lysis buffer at the bottom, working as a collection electrode. The sampler was operated with the sampling air flow rate of 40 L/min. Collection efficiency of the sampler is about 80% for 25nm to 5.0µm diameter particles. We sampled the air of a food court of a commercialdoi:10.21203/rs.3.rs-1236810/v1 fatcat:7ytfi7e7mnb4hk2yrh5onq4yza
