12 May 2016 Bioaerosol detection using single particle triggered LIBS
Author Affiliations +
A prototype LIBS system, measuring on single aerosol particles sampled from ambient air, has been developed for BWA detection purposes. To further discriminate measurement sampling, a 405 nm induced fluorescence trigger stage has recently been incorporated. The induced fluorescence, as well as the scattered light, was measured on monodisperse NADH and NaCl aerosols in the ~1-7 μm range as well as on dispersions of various simulant bioaerosols and interferents. Finally, the discrimination of sampling for LIBS measurements was demonstrated on NADH particulates in high non-fluorescent aerosol background.
