Quantifiable, infectious SARS-CoV-2 sampling with the BioSpot-VIVAS was shown in a fantastic new published article in Nature Scientific Reports by Alsved et al.

“Exhaled aerosol samples from SARS-CoV-2-infected individuals were collected in Feb-Mar 2021 using a condensational growth tube collector (BioSpot-VIVAS, Aerosol Devices Inc. operating at 8 L/min) while the individuals were either breathing, talking or singing, respectively, for 10 min each.”
