| Particle identification by intrinsic fluorescence | Prev topic | Next topic |
Kaye et al (2005) describe a prototype low-cost multi-channel aerosol fluorescence sensor for unattended operation. The sensor can characterize airborne particles down to ~1µm in size, flowing one-after-another through a sensing zone (as in a FCM) that is illuminated by a CW diode laser beam (660 nm). For each particle, the scattered light pulse triggers two xenon UV light sources (at ~280 nm and ~370 nm) for excitation of bio-fluorophores: tryptophan and NADH (nicotinamide adenine dinucleotide) respectively. The sensor can characterize up to ~125 particles/s.
