FIG. 2 Effect of the characteristic exposure temperature and the air flow rate through the test chamber on the inactivation of aerosolized MS2 virions. Points: experimentally obtained values of IF corrected (T e ); horizontal bars: range of [ttilde] air ; vertical bars: GSD of IF corrected . HPQL = Highest Practical Quantification Limit.
