Abstract:
Laser-induced fluorescence technique (LIF) is described for getting bacteria spectra in the liquid phase. An excimer laser pumping a dye-laser and a doubly frequency laser have been used, exciting the bacteria to 290 nm, and using a monochromator, 600 lines/mm grating, with a CCD to measure and obtain the fluorescence spectra. In this study, a laser induced fluorescence system to measure certain bioaerosols (bacteria) was optimised. Finally, a small bacteria fluorescence spectra collection is presented.
