Experimental results of inactivation of novel coronavirus (SARS-CoV-2) by ozone gas jets
[Collaborative research, Institute of Tropical Medicine, Nagasaki University]

Experimental Methods
A solution containing 0.1 ml of novel coronavirus was dropped onto multiple petri dishes placed in a chain bar with ozone gas or air flowing through it, and the petri dishes were collected over time and the amount of infectious virus remaining was quantified using a plaque assay.
Results of the Experiment
(1) In the absence of ozone gas (0.0 ppm), 24% of viruses remained viable after 150 min.
(2) In the presence of ozone gas (1.0 ppm), 97.6% of viruses were inactivated in 90 min, confirming the inactivating effect of ozone gas on SARS-CoV-2.

[in-house test]

Ozone concentration was measured in a room with a volume of 544 m3 by using the “Jet Fujin Large Scale” and verified that ozone was spread to every corner of the room.
