Andersen Sampling Efficiency\nThe novel virus collection methods employed on the Andersen sampler were comparable to each other in overall efficiency, and particle size fractionation capability, when SARS-CoV-2 was aerosolised from a Collison 6-jet nebuliser. Figure 3 shows the comparison in biological sampling efficiency for the three sampling methods employed. For all three, the majority of SARS-CoV-2 particles were collected on the lower stages of the sampler, \u003c3.3 µm. The liquids in the AGI samplers, collected from the Collison 6-jet (first study), contained 4.48 × 103 pfu/L, (standard deviation 2.39 × 103), which is comparable to the PFU/L collected by the Andersen methods: total PFU recovered across all stages, per litre of air sampled (with standard deviations) were: 27mL cMEM, 3.8 × 103 pfu/L (s.d. 2.7 × 103); 7 mL cMEM, 7.1 × 102 pfu/L (s.d. 6.9 × 102); and Gelatine, 2.0 × 102 pfu/L (s.d. 1.4 × 102). The total PFU/L across the three Andersen methods and AGI sampler were not significantly different (p = 0.241).","divisions":[{"label":"title","span":{"begin":0,"end":33}}],"tracks":[]}
