Table 1 Relative distribution of aerosol sizes: Each level of the Andersen impinger correlates with a diameter cut off [μm] given by the manufacturer.

From: Enhanced tenacity of mycobacterial aerosols from necrotic neutrophils

Level 1 2 3 4 5 6 7 8
Diameter cut off [µm] 8.0 6.5 5.2 3.5 2.6 1.7 1.0 0.22
Rel. distr. of mycobacteria [%] 0.4 0.8 1.4 2.9 9.4 27.3 40.6 17.1
Std. deviation 0.3 0.3 0.8 2.0 3.3 1.7 4.3 3.9
  1. The relative distribution of the mycobacteria was determined by electron microscopy (3 independent experiments with 100 bacterial cells assessed in each one).
