Abstract
Disclosed are systems are methods for identifying the composition of single aerosol particles, particularly that of bioaerosol particles. A continuous timing laser tightly coupled with a pulse ionization laser is used to index aerosol particles, measure particle properties, and trigger the ionization laser to fire when each particle enters the beam of the trigger laser. Ionized fragments and optionally photons produced when each particle is struck by the ionization laser are analyzed using one or more detectors including a TOF-MS detector and an optical detector. Individual single particle spectra are aligned and denoised prior to averaging.
