Laser Fluorescence Fingerprints of Environmental Materials

Source

A continuous wave (cw) and a pulsed-gated laser fluorescence systems were used to measure fluorescence spectra of polycyclic aromatic hydrocarbons (PAHs) thermally vaporized using an electrothermal atomizer. The cw laser was a Helium-Cadmium (He-Cd) laser and the pulsed laser was a flashlamp dye laser. The detector was an intensified photodiode array. Individual PAHs as well as PAHs produced by vaporizing crude oils, particulate matter and other samples were studied by this approach. Fingerprinting was performed by measuring three-dimensional plots of fluorescence intensity versus emission wavelength versus evolution temperature.
