Aerosol collectors 10, 120 include pre-collection filters 100, 126,
aerosol collection chambers 30, 130, and other exhaled breath
conditioning and control features for providing not only accurate and
efficient, but also reliable and reproducible aerosol collections that
can be used in standardizations and can be compared in meaningful ways to
other exhaled breath aerosol collections from the same test subject and
from different test subjects. The aerosol collector 10 example includes
electrostatic collection components 34, 40, and the aerosol collector 120
includes nucleating condensation components 168, 172 and vortex
collection components 132, 138. Both include analyte extraction apparatus
50, 124.
