Fluorescence preselection of bioaerosol for single-particle mass spectrometry

We have designed, constructed, and tested a system that preselects the biological fraction of airborne particles from the overall aerosol. The preselection is based on fluorescence emission excited by a continuous 266 nm laser beam. This beam is one of two cw beams used to measure the aerodynamic particle size of sampled particles. The intention...

Aerosol Time-of-Flight Mass Spectrometry: An approach to detect, select and identify biological aerosols

Method and device for detecting and identifying bio-aerosol particles in the air

In a method for detecting and identifying bioaerosol particles in the air, the bioaerosol particles in a particle stream are selected in an ATOFMS (aerosol time-of-flight mass spectrometer) by means of fluorescence techniques, and only the selected bioaerosol particles are ionized, for instance on the basis of MALDI (matrix-assisted laser...
